Abstract
A hermetic refrigeration rotary motor-compressor comprising a hermetically sealed pressure tight housing can enclosing a compressor unit comprising a housing having at least two axially spaced walls and rotatable in relation to the housing piston and cylinder-piston journaled on eccentric portions of two oppositely rotatable shafts. The piston and cylinder-piston form movable walls, and axially spaced walls of the housing form stationary walls of at least two compression chambers. The compressor unit may be operated by any suitable prime mover, preferably an electric motor. 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.
Claims16
A hermetic refrigeration rotary motor-compressor comprising:
- a multiple compression chamber compressor unit operatively positioned inside a hermetically sealed pressure tight housing can comprising:
- one or more two compression chamber modules, each comprising;
- A. a cylinder-piston comprising a body, two spaced walls extending from said body and having opposing parallel surfaces, and a wall interconnecting said two spaced walls at their ends remote from said body to form an opening in said cylinder-piston, said cylinder-piston further having two side faces and bearing means located in said body;
- B. a piston positioned within said opening of said cylinder-piston and having spaced faces adjoining said opposing parallel surfaces of said spaced walls of said cylinder-piston, said piston further having two spaced side faces and bearing means in said piston;
- C. two fixed spaced housing walls adjoining said side faces of said cylinder-piston and said spaced side faces of said piston;
- D. said cylinder-piston and said piston forming movable surfaces, and said fixed spaced housing walls forming stationary surfaces of two compression chambers located between said body of said cylinder-piston and said piston and between said piston and said wall interconnecting said two spaced walls of said cylinder-piston and varying in volumes upon coordinated planetary rotations in opposite directions of said cylinder-piston and said piston;
- intake means comprising intake ports leading to said compression chambers;
- discharge means leading from said compression chambers;
- a rotatable cylinder-piston shaft comprising an eccentric portion journaled in said body of each said cylinder-piston;
- a rotatable piston shaft comprising an eccentric portion journaled in each said piston;
- gearing means interconnecting said cylinder-piston shaft and said piston shaft so said shafts follow coordinated rotations in opposite directions and each said cylinder-piston and each said piston follow coordinated planetary rotations in opposite directions with and around said eccentric portions of said shafts;
- balancing means;
- lubricating means;
- a hermetically sealed pressure tight housing can;
- support means supporting said compressor unit in operative position inside said hermetically sealed pressure tight housing can;
- and
- prime mover means for driving said multiple compression chamber compressor unit.
