Abstract
The utility model relates to a rotary piston-type air compressor capable of automatically adjusting a compression ratio. The rotary piston-type air compressor is characterized in that a plurality of air cylinder chambers and pistons are uniformly distributed on a cylindrical air cylinder in a radial radiation manner, the axis of the cylindrical air cylinder is connected with a drive shaft, and a bearing is arranged outside the cylindrical air cylinder in a biasing manner. The piston rotates along with the air cylinder, and the air cylinder body makes reciprocating movement in the radial direction so as to complete the air suction, compression and exhaust process. Both an air suction port and an exhaust port are formed on the axis side of the air cylinder, a compression adjusting disc is arranged on the axis of the air cylinder and used for automatically adjusting the air compression ratio in the exhaustion, so that the pressure inside the compression chamber is equal to the pressure on the exhaust side. The air suction, compression and exhaustion process is continuous when the air cylinder rotates, the load is stable, so that the needed drive torque is reduced; and moreover, no air suction valve and exhaust valve are provided, the theoretical volume efficiency is 100 percent, no eccentric rotation exists, so that the compression efficiency is effectively improved, and the running vibration is alleviated. The rotary piston-type air compressor is applied to a closed-type motor drive compressor and a drive outboard compressor.

Embodiment:
Cylinder (1) live axle (4) drive under be rotated counterclockwise, piston (3) centrifugal action and biasing bearing (2) control under along radially to-and-fro motion of cylinder (1).In figure 01B, suction side piston (3a, 3b, 3c, 3d) is in suction condition; Compression and exhaust side piston (3e, 3f, 3g, 3h) are in compression and exhaust condition.
In figure 01B, the upper pressure chamber (5b) that arranges of compression adjustment dish (5), compression adjustment dish (5) is controlled by torsion spring (10) also.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 larger with pressure of inspiration(Pi) ratio, exhaust pressure and pressure chamber (5b) pressure difference is just larger, exhaust pressure promotes compression adjustment dish (5) and rotates counterclockwise, torsion spring (10) is compressed simultaneously, and when moment increases to counterclockwise balance state, compression adjustment dish (5) stops operating.On the contrary, if exhaust pressure reduces with 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), when exhaust starts, the indoor compression pressure of respective cylinder equals exhaust pressure, avoids the excess compression of air or the loss in efficiency that insufficient compression causes.Compression adjustment seat (16) is fixed on fixing axle bed (8), form sealing with fixed axle sleeve (9), fixed shaft cover (6) and pressure chamber (5b) wall, stop 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 upper running shaft that forms cylinder (1) of fixing axle bed (8) by fixing bolt (11), form sealing with cylinder (1) inner round wall, stop the gas of leaping up between cylinder block, or gas is revealed with exterior domain to relief opening.On fixing axle bed (8), have suction port (8b) and be communicated with suction tude (7), (3a, ab, 3c, 3d) all can be air-breathing in the time of suction side for piston.
Fixing axle bed (8), inner housing (13) and interior cap (14) are connected to form relative confined space, this space is connected with intakeport (8b) by oil gas attachment hole (8d), identical with pressure of inspiration(Pi) to ensure this confined space pressure, and discharge unnecessary lubricant oil in this confined space.Piston (3) can do smoothly centrifugal motion when air-breathing.
On cylinder (3) end face, arrange reversion self-locking grooves (1a), self-locking grooves (1a) forms self-locking inclination angle with cylinder (3) end face, steel ball (15) is placed in wherein, composition reversion self-locking device together with the upper steel ball groove (8c) of fixing axle bed (8).In the time stopping driving, can stop cylinder reversion to cause that pressurized air is back to suction side.
