Abstract:
PCT No. PCT/EP80/00036 Sec. 371 Date Dec. 9, 1980 Sec. 102(e) Date Dec. 9, 1980 PCT Filed Jun. 10, 1980 PCT Pub. No. WO80/02869 PCT Pub. Date Dec. 24, 1980.A circulator pump for a plant for the utilization of solar heat including a first heat exchanger for collecting heat at a high level disposed within a solar collector, a medium for receiving heat collected in the first heat exchanger, a second heat exchanger for collecting heat at a lower level with respect to the first heat exchanger and a circulator pump for circulating the medium through the first and second heat exchangers. The circulator pump is a prime mover driven by a pressure difference between the first and second heat exchangers and is a charger pump. The prime mover and charger pump operating in a push-pull manner as differential piston pumps having a common piston rod operatively disposed within a chamber including control ducts, which load an auxiliary control slider member. The auxiliary control slider member is reciprocated within a chamber and upon reaching end portions of the differential piston switch the chambers of the two differential piston pumps to effect oppositely directed movement.
