Abstract

Disclosed is an automatic compensation mechanism for a hinge seal gap in a spherical compressor. A cylindrical hinge is formed around a central pin (10), a rotating disk pin seat (81), and a piston pin seat (16) of the spherical compressor. A fan-shaped insert (14) thick at both sides and thinner in the center is disposed at the bottom of a sump (161) on the pin seat of the cylindrical hinge. The shape of the insert (14) matches the shapes of the sump (161) and of the external cylindrical surface of a semicylindrical element (811) on the pin seat of the cylindrical hinge respectively, forming a dynamic seal fit, thus improving the reliability of the seal, adapting to mass production, and enhancing overall performance.

• F04C 21/00 - Oscillating-piston pumps specially adapted for elastic fluids

Abstract

A spherical expansion compressor adapted to variable working conditions with a spherical inner chamber comprises a rolling rotor compressor used as first-stage compression, compression working chambers, expansion working chambers, a gas tank and a pressure control circuit. The pressure control circuit is arranged between the gas tank and a pressure-controlled inlet valve of the rolling rotor compressor, and controls the inlet valve to open/close according to the pressure in the gas tank. When the pressure in the gas tank is beyond a set value, the pressure-controlled inlet valve is closed by the pressure control circuit. When the pressure in the gas tank returns to the set value, the pressure-controlled inlet valve is opened and the rolling rotor compressor works normally. Working medium after first-stage compression enters the gas tank, the pressure in the tank maintains constant through the regulation of the pressure control circuit. Working medium with constant pressure enters second-stage compression, and then expands in the expansion-stage, thereby arriving at the spherical expansion compressor adapted to variable working conditions.

Abstract

A kind of compressor capable of implementing multistage compression is characterized by that several working chambers are set in a ball cylinder,the ball internal cavity has three movable elements: a piston (3), a dial (5) and a spindle (8). The air channel is set on the piston and piston hinge support (10), intake and exhaust channel is set on the cylinder body (1) and cylinder cover (2). When the piston is rotated into each working chamber and has need of in-taking air and exhausting air, the correspondent air channel is communicated with intake and exhaust channel so as to implement multi-stage compression and expansion.
