ABSTRACT:
A single cylinder pump for circulating cleaning fluids through a radiator or like cooling system applies positive and negative pressure to the fluid to create a pulsating agitation of the fluid through the radiator through the use of a thin washer-like plate which is reciprocatively driven within the cylinder. The washer-like plate is slightly smaller than the cylinder and is separated from the inside of the cylinder by a small annular clearance thereby eliminating the need for lubrication and permitting the pump to be self-priming and to release gases generated by the agitation of the fluids.
