Abstract:
A cruciform pump comprising a casing having and inlet and outlet, a position round disk in the casing; a driven rotary disk; and two sliding blocks; the positioning round disk having a cruciform sliding groove and a center of the positioning round disk being arranged to correspond to the center of the casing; the driven rotary disk being eccentrically installed on the positioning round disk; a shaft protruding from one surface of the rotary disk extends out of the casing; the two sliding blocks being connected to another surface of the rotary disk so as facilitate rotation of the positioning round disk; wherein when the driven rotary disk completes two circular rotations, the positioning round disk completes only one circular rotation, when the rotary disk and round disk rotate, the movement of the sliding blocks causes fluid to be sucked from the inlet into the sliding groove and then discharged from the sliding groove through the outlet.
