Valve unit for motor-vehicle, slip-controlled brake systems - has hydraulic non-return valve and solenoid valve mounted side-by-side but independent of each other

摘要

A valve unit for slip-controlled vehicle brake systems has a first hydraulic non-return valve (4) and a second solenoid valve (3), each being independent of the other. The two valves are situated side by side in a block (6) within the valve body (1). The lip of the casing partly overlaps the ball cavity (9) for the non-return valve. The inlet of the unit (13) connects with the pressure source, the outlet (12) with the brake cylinders. An alternative design for the valve has two separate blocks with different-sized passages overlapping each other and locating the balls. ADVANTAGE- Compact, easy to manufacture and assemble.
