Volumetric rotary compressor for refrigerator - has two spiral ducts of unequal section with mercury liquid pistons for heat pumps

摘要

Two parallel spiral ducts (17,18) of unequal sectional area, and of minimum polar course 3 pi radians, are contained in a plastic block (1) made in three assembled sections. The external and internal ends of the spirals are connected together, and also through chambers (6,8) to the outside. Mercury is placed in the ducts to form liquid pistons (14,15,16). A number of compressor elements can be placed in symmetrical satellite formation round a fixed rotational axis, to form at least one compressor, and the evaporator and condenser in a heat pump.
