Abstract (en)

[origin: DE19522448C1] The motor is particularly of the radial-piston type, having a non-rotating control member in the housing connecting the working chambers to high- and low-pressure unions. The valve (50) discharges into a pressure chamber (63) separate from the housing chamber (66). A valve (65) operated by the pressure in the pressure chamber connects the latter to the housing chamber. The fluid from the pressure chamber to the housing chamber flows via a device (73) restricting the flow rate. The valve connecting the pressure and housing chambers can be of type with seat, the pressure in the pressure chamber acting on it in the opening direction, its plug (67) being spring-loaded (79) shut.
