Abstract (en)
[origin: WO2007045519A1] Known devices have a valve housing in which a pressure release valve and a non-return valve are arranged parallel to one another, the pressure release valve having a first inlet, which downstream of a valve seat opens into a valve chamber in which a valve body is movably arranged and which is in fluid connection with a second inlet for the non-return valve via a first outlet. This has the disadvantage that the first outlet is arranged in the valve chamber in such a way as to result in an axial outflow from the valve chamber of the pressure release valve. Owing to the axial outflow, only a comparatively low impulse force is exerted on the valve body and thus only a comparatively small opening stroke for a given volumetric flow is executed. The control response is thus not optimum. The claimed device improves the control response of the pressure release valve. According to the invention, the first outlet (26.1) is provided at the periphery of the valve chamber (36) and is arranged in the axial direction with respect to a valve axis (38) such that when the pressure release valve (23) is open the flow from the valve chamber (36) into the second inlet (25.2) is a substantially radial flow.
