BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Oil filters of the kind which in addition to a filter part includes a cylindrical, often oblong container, are used for purifying the oil in engines of various types, e.g. diesel or petrol engines for trucks or the like. Such filters are at one of their ends provided with a threaded opening by means of which the container can be screwed into a connection to the lubrication system of the engine. When the oil in this system is changed the system is emptied through a plug or otherwise, for instance as disclosed in the Swedish patent application No. 8303510-5. The filter remains however filled with oil and if the filter also is to be changed in connection with the oil change, this can result in considerable difficulties when the filter is removed, which is normally done manually. Thus the oil runs over the edge and down the side of the filter container which causes the operator to lose his grip and to soil his hands with oil. The task of removing the filter is thus on one hand difficult to carry out in a convenient way and on the other hand harmful in so far that a repeated contact with oil, especially used oil, is harmful from a medical point of view.
BRIEF DESCRIPTION OF THE INVENTION
The present invention provides an arrangement and a method which removes the above-mentioned drawbacks and make possible a convenient quick and clean change of oil filter containers. According to the main features of the invention these and other objects are achieved in that to said container is associated a second container that is substantially empty when said first container is in a filled condition, and that a hole punching tool is arranged to make possible the opening of a draining hole in the first container before removal thereof so as to drain liquid from said first container to said second container whilst lowering the liquid level in said first container.
BRIEF DESCRIPTION OF THE ATTACHED DRAWINGS
In the drawings
FIG. 1 is a simplified section through an oil filter made in accordance with the invention and shown in a state of use,
FIG. 2 is a similar section showing the filter in connection with the removal thereof,
FIG. 3 is a partial section of a filter according to an alternative embodiment and
FIGS. 4 and 5 are perspective views showing two different embodiments of a hole punching tool.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
Throughout the drawings 1 generally denotes a conventional oil filter in the form of a container which includes a cylindrical wall 2 as well as a bottom 3. In the end part 4 being opposite to the bottom there is an opening with a thread (not shown) for screwing the filter container into the connection of the main compartment 50, shown here as a lubrication system of an engine. The container also includes a filter part (not shown) for filtering the oil passing through the container. As shown in FIG. 1 the container is normally entirely filled with oil 5 when connected to and forming a part of said lubrication system.
In accordance with the basic idea of the invention a second container generally denoted 6 is associated to the filter container 1, said second container in this case being mounted to the bottom end of the container 1 and extending in extension thereof. Thus the container 6 too includes a cylindrical wall 7 as well as a bottom wall 8, said cylindrical wall 7 being fitted onto the outer side of the container 1 and in a suitable manner sealingly connected thereto e.g. by means of a sealing ring 9.
To make it possible to make a hole in the bottom wall 3 of the container 1 a hole punching tool associated to the second container 6 and in the form of a striking pin 10 is mounted in a sleeve extending inwardly from the bottom 8, a sealing ring 12 being connected to said sleeve in order to seal the area between the inside of the sleeve and the outside of the striking pin. Advantageously the pin 10 on its free end protruding from the container 6 is provided with an actuating means, which here takes the form of a plate 13 against
