Patent ID: 8205634

Claim:
A hydraulic block ( 24 ) for an automatic transmission of a motor vehicle, comprising: at least one valve socket ( 44 ) for accommodating a valve body of a pressure control valve or switching valve ( 10 ) and a hydraulic medium at an inlet pressure on an inlet side ( 30 ); a moveable valve closure member ( 12 ) disposed in the valve body ( 20 , 66 ), wherein said valve closure member ( 12 ) acts on a closure element ( 16 ), wherein the closure element ( 16 ) cooperates with a closure seat ( 18 ) formed on the valve body; at least one annular seal ( 52 , 54 ) encompassing the valve body ( 20 , 66 ) of the pressure control valve or switching valve ( 10 ) in the region of the at least one valve socket ( 44 ), wherein the at least one annular seal ( 52 , 54 ) is integrated in a wall ( 70 ) of the hydraulic block ( 24 ) and has an elasticity resulting from a material of the hydraulic block ( 24 ) and at least one annular chamber ( 60 , 62 ) that engages behind the at least one annular seal ( 52 , 54 ), such that the at least one annular seal ( 52 , 54 ) integrated in the wall ( 70 ) of the hydraulic block is disposed elastically on a circumference of the valve body and thereby forms a sealing surface ( 74 ).
