Abstract
The invention discloses a rotary piston type air compressor capable of regulating the compression ratio automatically. A plurality of cylinder chambers and pistons are uniformly and radially distributed on a cylindrical cylinder in the radial direction; the axis of the cylindrical cylinder is connected together with a drive shaft; a bearing is offset outside the cylindrical cylinder. The pistons rotate with the cylinder and have reciprocating movement as well along the radial direction of the cylinder body so as to finish inhaling, compression and exhausting. An inhaling port and an exhausting port are both in the axis side of the cylinder; a compression regulating disc is arranged in the axis of the cylinder for automatically regulating the air compression ratio during exhausting, so that the pressure in a compression chamber is equal to that at the exhausting side during exhausting. When the cylinder rotates, the inhaling, compression and exhausting are continuous; the load is stable; the needed driving moment is reduced; moreover, no inhaling and exhausting valves are arranged, the theoretical volumetric efficiency is 100%, and no eccentric rotation is caused, so the compression efficiency is improved and vibration caused in operation is reduced. The rotary piston type air compressor disclosed by the invention is used for a closed motor driven compressor and an external driven compressor.

Embodiment:
Cylinder (1) is rotated counterclockwise under live axle (4) drives, and piston (3) is in the radially to-and-fro motion of control lower edge cylinder (1) of centrifugal action and biasing bearing (2).Among Figure 1B, (3c 3d) is in suction condition to the suction side piston for 3a, 3b; (3g 3h) is in compression and exhaust condition for 3e, 3f for compression and exhaust side piston.
Among Figure 1B, compression adjustment dish (5) is gone up and is arranged that a pressure chamber (5b), compression adjustment dish (5) also are subjected to torsion spring (10) control.Pressure chamber's (5b) air pressure and torsion spring (10) provide compression adjustment dish (5) moment of torsion clockwise; Compression adjustment dish relief opening (5a) pressure provides compression adjustment dish (5) moment of torsion counterclockwise; Pressure chamber (5b) is communicated with prime compression cylinder chamber (3e present position), and exhaust pressure is the multiple of pressure chamber (5b) pressure; Exhaust pressure is bigger than more with pressure of inspiration(Pi), exhaust pressure and pressure chamber (5b) pressure difference is just more big, exhaust pressure promotes compression adjustment dish (5) and rotates counterclockwise, and torsion spring (10) is compressed simultaneously, moment increase to and counterclockwise during the balance state compression adjustment dish (5) stop operating.On the contrary, if exhaust pressure reduces with the pressure of inspiration(Pi) ratio, pressure adjustment disk (5) will be rotated clockwise to new balance position.Under the regulating action of pressure adjustment disk (5), the indoor compression pressure of respective cylinder equaled exhaust pressure when exhaust began, and avoided the excess compression of air or the loss in efficiency that insufficient compression causes.Compression adjustment seat (16) is fixed on fixedly on the axle bed (8), forms sealing with fixed axle sleeve (9), fixed shaft cover (6) and pressure chamber (5b) wall, stops exhaust side gas to enter pressure chamber (5b).
Fixed axle sleeve (9), compression adjustment dish (5) and fixed shaft cover (6) are axially fixed in the fixedly last running shaft that forms cylinder (1) of axle bed (8) by fixing bolt (11), form sealing with cylinder (1) inner round wall, stop the gas of leaping up between the cylinder block, or gas is revealed with exterior domain to relief opening.Fixedly have suction port (8b) on the axle bed (8) and be communicated with suction tude (7), (3c 3d) all can be air-breathing for 3a, ab when piston was in suction side.
Fixedly axle bed (8), inner housing (13) and interior cap (14) are connected to form relative confined space, this space links to each other with intakeport (8b) by oil gas attachment hole (8d), identical with pressure of inspiration(Pi) to guarantee this confined space pressure, and discharge unnecessary lubricant oil in this confined space.Piston (3) can be done centrifugal motion smoothly when air-breathing.
Arrange counter-rotating self-locking grooves (1a) on cylinder (3) end face, self-locking grooves (1a) forms the self-locking inclination angle with cylinder (3) end face, and steel ball (15) is placed in wherein, goes up steel ball groove (8c) with fixing axle bed (8) and forms the counter-rotating self-locking device.When stopping to drive, can stop the cylinder counter-rotating to cause that pressurized air is back to suction side.
In embodiment illustrated in fig. 2, motor (15) places in the confined space of capsul (20), capsul loam cake (21), capsul lower cover (19) composition; Fixedly relief opening (8a) links to each other with compression adjustment dish outer vent (5b) and the last outer vent of fixed shaft cover (6) on the axle bed, leads to the outer vent (4a) on the live axle; Discharge gas blow motor coil (17b) and rotor (17a) and discharged by outlet pipe (18), and take away the motor heat.Because load is stable, the demand drive power square little and improve electric efficiency, no air valve step-down loss, volumetric efficiency height, sliding friction few, rotate without acceptance of persons, thereby effectively improve compressor efficiency, reduce and vibrate.
In the embodiment shown in fig. 3, fixedly on the axle bed outer vent is set, outlet pipe (18) is connected on this outer vent, and fixedly relief opening (8a) directly leads to outlet pipe discharge pressurized air on the axle bed, on fixed shaft cover (22) and the external Power Available Shaft (23) outer vent is set no longer.Because load is stable, the demand drive power square little and reduce few to the interference of external power source, no air valve step-down loss, volumetric efficiency height, sliding friction, rotate without acceptance of persons, thereby effectively improve compressor efficiency, reduce and vibrate.
