Abstract
PURPOSE:To produce a compact and small-sized liquid pressure device, by inserting a cylindrical valve into a valve casing located at one side of a gerotor casing while forming the first and second oil paths in said valve. CONSTITUTION:A valve casing 4 is located at one side in axial direction of a gerotor casing 1, where a thick cylindrical valve 5 is inserted rotatably in said casing 4 while the first oil paths 51a-56a and the second oil paths 51b-56b are formed in said valve 5. Since only one valve is required while the first and second oil paths are employed as go and return oil paths, a compact and small-sized liquid pressure device can be achieved.
