MODE OF OPERATION OF COMPRESSOR PUMP AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC F04B39/04 

FIELD: motors and pumps.

SUBSTANCE: before change of fluid the hydraulic circuit and jackets enclosing a compressor cavity are cleaned, and for moving of cleaning environment the move of working medium of a pump cavity is used, and atmospheric air can be used as a cleaning medium. The compressor pump for a implementation of this method consists of a crankcase 1 with mechanism 2 for moving the piston 3, where the crosshead guide 4 is built-in 4, which functions simultaneously as an internal wall of the pump cavity 5. The function of external wall of the cavity 5 is executed by an internal wall of the cylinder 6, which is also a wall of the compressor cavity 7 with intake valve 8 and filter 9, delivery valve 10, receiver 11 and filter 12. The pump cavity 5 can be connected to reversing valve 16 through output 17 and then through input 18 with atmosphere through the filter 19 and then through input 30 with output 31 with the vessel 22 or with output 32 and further with entry into the refueling device 33, supplying the fluid 26 to consumer. At reciprocal motion of the piston 3 the volumes of compressor 7 and pump 5 cavities are changed, after that air is sucked into cavity 7 through the valve 8, compressed and supplied to the consumer through the valve 10.

EFFECT: intense cooling of compressor cavity and a possibility for supply to consumer of fluids significantly varying by composition and excluding even insignificant mixing that expands the scope of applicability of the compressor pump.
