ABSTRACT:
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. The hydraulic unit 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 is composed of a resilient element (28) that is clamped into the side wall (33) of a depression of 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). The present hydraulic unit provides significant size reduction of the valve-accommodating member (13) in that the hydraulic components such as the non-return valves which are normally disposed in the interior of the valve-accommodating member (13) are placed into the outside wall of the valve-accommodating member (13).
