ABSTRACT:
A reciprocating type pump has a pair of body members with complementary concave and convex surfaces which clamp a flexible sheet means therebetween to hold the same in curved configuration. The member having the convex surface has a pump chamber opening toward the flexible sheet means and the concave member has inlet and outlet passages opening toward the flexible sheet. The flexible sheet has portions overlying such inlet and outlet passages and the overlying portions have free edge portions extending in the direction of curvature of the flexible sheet and adapted to be flexed toward said convex surface member by fluid pressure from said passages whereby the overlying portions of the flexible sheet are reversely curved under the force of said fluid pressure and return resiliently to original passage closing condition when such pressure is not acting thereagainst.
