<p>A cup-shaped diaphragm (21) is inserted into a bore (10) formed in a housing (1). An inlet opening of the bore (10) is closed by a plug-like wall member (12). A conduit line (S) extends obliquely with respect to an axis of the bore (10) from an annular space (13b) formed between a cylindrical wall of the bore (10) and a protruding portion (12a) of the plug-like wall member (12). The annular space (13b) is connected to a pressurizing control valve (2) via the conduit line (S). A chamber (13a), partitioned from the annular space (13a) by the cup-shaped diaphragm (21), serves as a damper chamber which has a diameter substantially equivalent to a diameter of the bore (10). <IMAGE></p> |
