Abstract: A fluid pressurization apparatus utilizing a slanted cam disk to oscillate, or to oscillate and rotate a set of piston assemblies arranged in a circle. The motion of the pistons is utilized to pressurize fluid or to perform work. The piston assemblies have multiple elements configured to allow the plungers to be engaged or disengaged to the motion of a disk by manipulating a working fluid introduced into the apparatus. By virtue of these disengageable plungers, the apparatus can be disabled and resumed at will. This apparatus is particularly well suited for pressurizing liquids such as water for high-pressure and high-flow applications.

Abstract: An axial plunger slurry pump comprises a pump body, a sloping cam plate, a swashplate, cylinders, plungers and a pump head. Each of the plungers comprises a plunger body with a rubber piston positioned in its front end and being able to slide over it, and an oil receiving gap communicating with an oil passage disposed between two facing end surfaces of the plunger body and the rubber piston. There are check valves each of which is provided in an oil passage between a ball of each of two-ball links, which ball is coupled with the swashplate, and the swashplate. Each of the cylinder and the plunger body are fitted together by means of a half-and-half locating pad, a cylinder sleeve, a pressing cap, and a locking device. The pump may be used widely in drilling, electric power, mine, building, and metallurgy, etc., for conveying mud, mortar, ore pulp, coal pulp, concrete, etc.
