Abstract

PURPOSE: To prevent the valve plates from leaking by interposing seal members to extend in the radial direction in the boundary for the inlet side and the discharge side of the sliding contact faces of the fixing valve plate and the movable valve plate, in a rotary valve type plunger pump to feed muddy material, such as concrete, etc. under pressure.
CONSTITUTION: Seal members 39 are arranged in a bursting-star pattern to interrupt between a long hole 9 for the discharging purpose of the fixing plate 8 and a long hole 10 for its inlet purpose. The seal members 39 are inserted into radial grooves 40 which are provided on the body 2 and the fixing plate 8, and thrust always on the side of the movable plate 11. When a circular hole 12 of the movable arrives at the no-hole position of the fixing plate 8, approximately 60% to 90% on the area of the circular hole 12 is determined to form an angle θ as much as to be positioned between the two seal members 39.
