ABSTRACT:
A valving member is carried within the bore of a meter body having inlet and outlet ports. Chambers are formed within the bore on opposite sides of a piston slideably disposed about the valving member. In response to movement of the piston, valving member shifts axially within the bore to establish sequential periodic communication between alternate chambers and the inlet and outlet ports. After each shift, the valving member is latched by magnetic means.
