Abstract

A double membrane pump for the circulation of water forming part of a solar heating system, has two heat exchangers (14, 14') connected to a main distributor valve (DP) and to opposite sides of a double acting pump (30) between the two membrane pump portions (4, 4'). The two membranes (6, 6') are subjected to differential pressure from the fluid and form with the frame (5) a discharge chamber (40, 40') for the water to a double membrane pressure transformer. The common control spindle (T) for the membranes is attached to a piston inside a reinjection pump (20) connected to the multiple plate combines evaporator and condenser for a refrigeration fluid circuit. At the other end of the spindle is a pilot distributor valve (27) which operates the main distributor (DP).
