| description | In a fluid pressure control valve apparatus (1), a stepped bore (4) is made in a main body (2), in communication with input and output openings (23,24). A cover member (5,13) is inserted in the input opening (23) with a stepped piston (8) slidably fitted into the stepped bore (4). A path (9) is formed in the stepped piston (8), one end of the path communicating with a through hole (5a) of the cover member (5,13) and another end of the path communicating with the output opening side; a valve seat (11) is formed at the one end of the path (9). A valve body (14) is seatable on, and separable from, the valve seat (11) and is arranged in a valve chamber (10) formed in the through hole (5a). A retainer member (16,33) is arranged at the input opening side of the cover member (5,13), supporting one end of a valve spring (17); a pre-loaded spring (12) biases the stepped piston (8) away from the valve body (14). An annular thin projecting portion (18) is formed integrally with the main body (2) at the input opening side, projecting outwards from the end of the cover member (5,13) such that the cover member (5,13) is fixed to the main body (2) by deforming plastically the annular thin projecting portion (18) towards the cover member (5,13). An outer circumferential portion (16a,33a) of the retainer member (16,33) is held between the deformed annular thin projecting portion (18) and the cover member (5,13). |
