Abstract:
A valve unit for modulating pressure in a compressed-air brake system comprises an inlet valve ( 6 ) and an outlet valve ( 7 ) configured as diaphragm valves, a brake pressure output ( 4 ) configured to be connected to or shut off from a brake pressure input ( 3 ) or a vent output ( 5 ), two pilot valves ( 8, 9 ) configured as 3/2-way solenoid valves, and a respective control chamber ( 31, 32 ) adjacent to the diaphragm ( 17, 18 ) of the diaphragm valves ( 6, 7 ). The diaphragms ( 17, 18 ) are each clamped between two housing parts ( 11, 14; 11′, 14 ′) via a respective ring bead ( 22, 23 ) placed in a housing-side ring groove ( 20, 21; 20′, 21 ′). In order to avoid damaging the diaphragms ( 17, 18 ), an annular continuous or partially interrupted recess ( 54 ) is arranged in the ring groove ( 20, 21 ) or immediately adjacent to the ring groove to receive displaced bead material from the diaphragm ( 17 ).

Claim (Index 9):
The valve unit as claimed in  claim 8 , wherein the edge groove ( 68 ) has a single step and the annular continuous recess ( 71 ) is formed by a radial groove ( 73 ) arranged in a radial side wall ( 72 ) of the radially outer groove portion ( 70 ) of the edge groove ( 68 ).
