WHEEL VALVE DEVICE WITH SAFETY VALVE CAP Russian patent published in 2017 - IPC B60C23/00 

FIELD: automotive engineering.

SUBSTANCE: invention relates to the wheel valve device of the actual pressure matching device in at least one tire with specified pressure in the tire, with a feed connection made on the body, in which either setting of the specified pressure in the tire is carried out to match the actual pressure in the tire with the given pressure in the tire, or deaeration if the actual tire pressure corresponds to specified tire pressure. According to the invention, the safety cap of the closing valve of at least the control membrane and the valve stem rest against the body or against the ring located on the body. The safety cap of valve contains at least one recess closed by deaeration element, in order to provide load of at least one control membrane with atmospheric pressure. In this way, the safety cap of the valve prevents the ingress of coarse impurities and moisture and thereby protects the control membrane and the valve stem, in particular, during operation of a vehicle on the road. At least one recess closed by the deaeration element ensures the influence of atmospheric pressure on the control membrane.

EFFECT: increased reliability of the wheel valve also during operation of the vehicle on the road under the action of dirt, water, ice and snow.
