BRIEF SUMMARY
DESCRIPTION
The invention relates to a watering valve for small animals, especially chickens, having a housing which is connectable to a water supply means and a valve pin and, above the valve pin, an upper pin located in the housing, the upper pin and the part of the housing associated therewith forming a flow restriction section.
This type of watering valve is used for the keeping of livestock on a large scale, preferably of small animals such as chickens, and enables the small animals to independently satisfy their need for water. The watering valve is opened by moving a valve pin disposed therein from the actuating end of the pin, and the watering valve is closed automatically as soon as the small animal breaks off contact with the actuating end of the valve pin.
Such a watering valve is already known from DE-GM 88 04 053. This valve has a housing which is connectable to a water supply means and a valve pin mounted in the housing and comprising an actuating end projecting from the housing. The valve pin is liftable or pivotable for the release of drinking water. A cylindrical upper pin is arranged above the valve pin and is axially displaceable within an enlarged bore portion of the housing. The upper pin and the part of the housing which is associated therewith form a flow restriction section which sets the flow rate of the water to a certain value. As a result, a constant flow of water flows out of the watering valve whenever the valve pin is actuated. As the animals grow, their need for water changes. The known watering valve does not allow for this changing need for water as it only dispenses a certain quantity of water per unit of time. As a result, the drinking water supply does not correspond to the needs of the animals, which is a drawback especially for the keeping of livestock on a large scale. Small chicks, for example, are provided with too much water when they actuate the watering valve, whereas the water needs of older birds can only be satisfied with long drinking periods.
In view of the foregoing, the invention is based on the object to create a watering valve of the type described above which ensures a water supply which meets the water needs of the animals, especially of animals of different ages, by simple means.
According to the invention, this object is attained by forming a variable flow restricting section from the upper pin and the part of the housing associated therewith. As a result, tile quantity of water flowing out of the watering valve per unit of time can be varied in a simple manner, i.e. it can be adapted to tile needs of the animals.
In a preferred embodiment of the invention, the upper pin has a plurality of portions having different cross sections. The cross sect ions are selected such that the upper pin can be inserted into the housing in different relative positions.
Preferably, the cross sections of the portions have an identical geometric shape but a different surface area. Because of technical reasons, the cross sections of the portions have a preferably circular shape, i.e. the upper pin is a recessed cylindrical pin.
The flow restriction section of the watering valve is formed from the portion of the upper pin which has a greater surface area and the associated part of the housing, or, to be more precise, from the length of the portion with the greater diameter which interacts with the housing. The flow restriction effect with respect to the quantity of water flowing through the watering valve is based on the small annular gap between the housing and the portion of the upper pin which has the greater surface area. According to the findings of the invention, however, the flow restriction effect depends above all on the length of the portion with the greater surface area which interacts with the housing. A greater length effects a small water flow rate and vice versa. A change of the water flow rate can thus be attained by a variation of the relative position of the upper pin in the housing. For this purpose, the upper pin only has to be reversed in the housing
