Abstract

PURPOSE:To make improvements in the durability of a pressure responding body by housing a working medium at the cylinder side partitioned off by the pressure responding body, and installing a selector in a passage lying between this body and a valve chest. CONSTITUTION:When an elastic film 23 is contracted by suction operation of a plunger 3, volume at the cylinder side A of a pressure working chamber 5a is contracted as well, and an amount of fluid 14 conformed to this contraction flows into a valve chest 1. At this time, such one as being more than the specified grain size is removed by a valve seat 11 and its inflow into the valve chest 1 is checked. In the fluid 14 taken into the valve chest 1, such one as being more than the specified grain size can not pass through a selector 19, so that no grain gets into a valve chest side B of the pressure working chamber 5a. Next, the elastic film 23 is expanded by pressing operation of the plunger 3, thereby feeding the fluid 14 taken into the valve chest 1 to the outside of the valve chest 1 with pressure.
