<p>A hydraulic unit for a hydraulic controlling or regulating device, in particular for a braking pressure regulating device in anti-lock control systems or traction slip control systems for automotive vehicles, comprises a valve-accommodating member (13) accommodating electromagnetically switchable valves. Hydraulic channels (23) are contained in the valve- accommodating member. Incorporated in the side wall of the valve-accommodating member (13) is a non-return valve which comprises a resilient element (28) that is clamped into the side wall (33) of a depression in the outside wall of the valve-accommodating member (13). The resilient element (28) is made of spring steel and is furnished with sealing material (34). A connector (25) e.g. a hydraulic circuit board is attached to the outside wall of the member (13). Many non-return valve constructions are disclosed (Figs 4-11, not shown). <IMAGE></p> |
