Abstract
A hermetic refrigeration rotary motor-compressor comprising a hermetically sealed pressure tight housing can enclosing a compressor unit comprising rotary cylinder-piston and piston elements journaled on eccentrics of two oppositely rotatable shafts, and a motor unit for driving the compressor unit having a rotor mounted on one of the compressor unit shafts, with a stator of the motor unit positioned in operative relation to the rotor of the motor unit. The piston and cylinder-piston form moveable walls, and two axially spaced walls form stationary walls of a compression chamber. An intake charge of refrigerant vapor may cool the motor unit and is admitted into the compression chamber through intake ports and discharged through a system of discharge valves into the discharge line.
Claims15
A hermetic refrigeration rotary motor-compressor comprising:
- a compressor unit operatively positioned inside said hermetically sealed pressure tight housing can, said compressor unit comprising:
- a cylinder-piston comprising a body and spaced arms extending from one end of said body, said spaced arms having opposing parallel surfaces and forming with said body of said cylinder-piston a U-shaped opening;
- said cylinder-piston further comprising bearing means located in said body of said cylinder-piston and having two side faces;
- a piston positioned within said U-shaped opening of said cylinder-piston and having spaced faces adjoining said opposing parallel surfaces of said spaced arms of said cylinder-piston;
- said piston further comprising bearing means and having two spaced side faces;
- two walls;
- spacing means axially spacing said two walls to said axially spaced walls adjoin said side faces of said cylinder-piston and said spaced side faces of said piston;
- a rotatable cylinder-piston shaft comprising an eccentric portion journaled in said bearing means located in said body of said cylinder-piston;
- a rotatable piston shaft comprising an eccentric portion journaled in said bearing means located in said piston;
- said two axially spaced walls further comprising bearing means for journaling of said rotatable cylinder-piston and said piston shafts;
- gearing means interconnecting said cylinder-piston shaft and said piston shaft so said shafts follow coordinated rotations in opposite directions and said cylinder-piston and said piston follow coordinated planetary rotations in opposite directions with and around said eccentric portions of said shafts;
- said cylinder-piston and said piston forming moveable surfaces, and said axially spaced walls forming stationary surfaces of a compression chamber located between said body of said cylinder-piston and said piston and varying in volume upon said coordinated planetary rotations in opposite directions of said cylinder-piston and said piston;
- intake means comprising an intake port leading to said compression chamber;
- discharge means comprising a discharge valve and leading from said compression chamber;
- balancing means;
- lubricating means;
- a hermetically sealed pressure tight housing can;
- a support for supporting said compressor unit in operative position inside said hermetically sealed pressure tight housing can;
- and,
- a motor unit for driving said compressor unit, comprising:
- a rotor operatively attached to one of said cylinder-piston or said piston shafts;
- a stator;
- and,
- a supporting means for supporting said stator of said motor unit in operative relation to said rotor of said motor unit and to said compressor unit.
