Embodiment 1

[0034] Embodiment 1: A cock type double-cylinder rotary compression mechanism.

[0035] image 3Shown is a plug-type twin-cylinder rotary compression mechanism. In the figure, a plug-type double-cylinder rotary compression mechanism composed of two convex plugs 5 and two cocks 6 is used; the two convex plugs 5 isolate the annular closed space into two arc-shaped working chambers (double cylinders) , The convex plug 5 works in the gas isolation mode, and the two sides of the convex plug 5 are provided with an air inlet 10 and an exhaust port 11; the side plates are fixed on both ends of the base cylinder of the rotor 3, forming the main body of the cock type double-cylinder rotary compression mechanism. The rotor 3 drives the cock 6 to rotate continuously at a constant speed, the rotation speed ratio between the rotation of the rotor 3 and the reverse rotation of the cock 6 is 1:1 (the relative speed ratio between the cock 6 and the rotor 3 is 2:1), and the rotor 3 rotates onc...

Abstract

The invention relates to a cock-type rotary compression expansion mechanism comprising a stator, a rotor, projecting plugs, and cocks. A base circle hole is provided at the center of the stator, and more than one projecting plugs are arranged on the periphery of the base circle hole. The rotor is a base circle column. A central main axis of the rotor is positioned at the center of the stator base circle hole through an end cap. More than one cock slots are provided on the base circle column. The cocks are placed in the cock slots; a sealed hollow chamber is formed between the stator base circle hole and the rotor base circle column. The top of the projecting plug is slidably connected with the rotor base circle. Cock outer circles are slidably connected with the stator base circle and the cock slots. The projecting plugs and the cocks separate the sealed hollow chamber between the stator base circle hole and the rotor base circle column into more than two independent sealed working chambers. Transposition slots are arranged on the cock. During rotation transposition, the back ends of side edges of the transposition slots are slidably connected with the back sides of the projecting plugs, and the front ends of the side edges of the transposition slots are slidably connected with the front sides of the projecting plugs, such that working gas is sealed in the transposition slots. The mechanism provided by the invention can be used in devices such as compressor, expander, internal combustion engine, heat pump, and the like.

Description

technical field [0001] The invention relates to a variable capacity compression expansion mechanism, in particular to a variable capacity rotary compression expansion mechanism. Background technique [0002] Since the invention of the reciprocating compressor and the internal combustion engine, in order to overcome the shortcomings of the reciprocating compression and expansion mechanism, such as large operating vibration, low mechanical efficiency, and relatively large volume, people have been constantly looking for a compression and expansion mechanism that uses rotary motion instead of reciprocating motion. A large number of devices of various styles have been invented. For example: gear-gear mechanism, convex-concave mechanism, eccentric wheel or cam-slide mechanism, eccentric wheel or cam-swing door mechanism, slip ring-slide mechanism, impeller-revolving door mechanism, axial convex-concave mechanism, eccentric rotor-rotary Wheel-line cavity mechanism, scroll movement...
