<p>In a control valve (1), an operating rod (19) and a shaft (36) are rigidly connected to each other through a housing (81) of a power element (4) but not through a resilient member, etc., so that a solenoid force is directly transmitted to a valve body (18) of a main valve. Accordingly, when a solenoid (3) is supplied with a starting current, the main valve can be immediately closed. A valve seat (17) for the main valve and a valve body (21) of an auxiliary valve are formed integrally with a valve forming member (15) and the valve forming member (15) functions also as a movable valve seat, and hence, the auxiliary valve can be opened at the same time as the closure of the main valve.</p> |
