Controllable diaphragm valve, especially for a windshield washer system in Motor vehicles

The innovation concerns a controllable ring diaphragm valve, that essentially consists of a sleeve-shaped valve body with two Sehlauoh connection pieces and a ring membrane consists, wherein in the flow channel of the valve body a Guide part and side openings are provided in the valve body in the vicinity of the guide part »when the valve is not actuated Ringraombranventil through the ring membrane against the flow openings of the hose connection paws completely are sealed, especially for a windshield washer system in motor vehicles in which the washing liquid is under excess pressure.

It is a Riug diaphragm valve known that pneumatically or hydraulically controllable and with (learning in the flow channel a guide body is provided, both of which are seldom the flow channel has openings through a Annular diaphragm are covered. In this version, the ring diaphragm is surrounded by a housing that is connected to the ring
