ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to devices for controlling the RPM of a combustion engine and more particularly pertains to a new engine throttle control device for permitting a user to control the opening and closing of the throttle valve of a carburetor (or the fuel pump of a diesel engine) remotely from the passenger compartment of the vehicle to increase the RPM of the engine.
2. Description of the Prior Art
The use of devices for controlling the RPM of a combustion engine is known in the prior art. More specifically, devices for controlling the RPM of a combustion engine heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 4,577,603 by Murakami et al.; U.S. Pat. No. 5,333,585 by Kuroda; U.S. Pat. No. 4,938,180 by King; U.S. Pat. No. 4,838,223 by Tanabe et al.; U.S. Pat. No. 4,261,308 by Hadekel et al.; and U.S. Pat. No. Des. 298,228 by Hoshino which are all incorporated by reference herein.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new engine throttle control device. The inventive device includes a pivotally mounted actuator arm pivotable at a pivot axis between a first and second pivot positions. The actuator arm is operatively connected to a fuel delivery device for delivering fuel to a combustion engine. The delivery of fuel to the combustion engine by the fuel delivery device is increased as the actuator arm is pivoted towards the first pivot position. Conversely, the delivery of fuel to the combustion engine by the fuel delivery device is decreased as the actuator arm is pivoted towards the second pivot position. A motor is connected to the actuator arm for pivoting the actuator arm between the first and second pivot positions. The motor has a remote controller switch electrically connected thereto to permit selective activation of the motor.
In these respects, the engine throttle control device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of permitting a user to control the opening and closing of the throttle valve of a carburetor (or the fuel pump of a diesel engine) remotely from the passenger compartment of the vehicle to increase the RPM of the engine.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of devices for controlling the RPM of a combustion engine now present in the prior art, the present invention provides a new engine throttle control device construction wherein the same can be utilized for permitting a user to control the opening and closing of the throttle valve of a carburetor (or the fuel pump of a diesel engine) remotely from the passenger compartment of the vehicle to increase the RPM of the engine.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new engine throttle control device apparatus and method which has many of the advantages of the devices for controlling the RPM of a combustion engine mentioned heretofore and many novel features that result in a new engine throttle control device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art devices for controlling the RPM of a combustion engine, either alone or in any combination thereof.
To attain this, the present invention generally comprises a pivotally mounted actuator arm pivotable at a pivot axis between a first and second pivot positions. The actuator arm is operatively connected to a fuel delivery device for delivering fuel to a combustion engine. The delivery of fuel to the combustion engine by the fuel delivery device is increased as the actuator arm is pivoted towards the first pivot position. Conversely, the delivery of fuel to the combustion engine by the fuel delivery device is decreased as the actuator arm is pivoted towards the second pivot position. A motor is connected to the actuator arm for pivoting the actuator arm between the first and second pivot positions. The motor has a remote controller switch electrically connected thereto to permit selective activation of the motor.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new engine throttle control device apparatus and method which has many of the advantages of the devices for controlling the RPM of a combustion engine mentioned heretofore and many novel features that result in a new engine throttle control device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art devices for controlling the RPM of a combustion engine, either alone or in any combination thereof.
It is another object of the present invention to provide a new engine throttle control device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new engine throttle control device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new engine throttle control device which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such engine throttle control device economically available to the buying public.
Still yet another object of the present invention is to provide a new engine throttle control device which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new engine throttle control device for permit
