Title: DIAPHRAGM NON-RETURN VALVE FOR A COMPRESSED AIR SYSTEM
Abstract:
The invention relates to a diaphragm non-return valve (1, 101, 201) for a compressed air system, having a housing (11; 111; 211), a ventilation outlet (2; 102; 202) formed on the housing (11; 111; 211), a valve seat (5; 105; 205) formed on the ventilation outlet, and a diaphragm disc (12; 112; 212) which is secured to the housing (11; 111; 211) and which lies on the valve seat (5; 105; 205) in the closed state of the non-return valve (1; 101; 201) and which is lifted off the valve seat (5; 105; 205) in the open state of the non-return valve (1; 101; 201). The aim of the invention is to increase the functional reliability and simplify the assembly of the non-return valve. According to the invention, this is achieved in that the diaphragm disc (12; 112; 212) is secured to the housing (11; 111; 211) by means of a clamping bracket (16; 116; 216), and the clamping bracket (16; 116; 216) has holding means (17, 18; 117, 118; 217, 218), by means of which the clamping bracket is secured to the outlet-side end of the ventilation outlet (2; 102; 202).
