Structure (for example, rolling piston compressor or rolling-piston-type expanding machine), swing-rotor type mechanism are (for example, swing-rotor type pressure
Contracting machine or swing-rotor type expanding machine), single working chamber slide sheet type mechanism is (for example, single working chamber sliding-vane compressor or either simplex are made
Chamber sliding vane type expander), Double working chamber slide sheet type mechanism is (for example, Dual-cavity sliding vane type compressor or Double working chamber slide sheet type
Expanding machine), penetration slipping sheet formula mechanism (for example, penetration slipping sheet formula compressor or penetration slipping sheet formula expanding machine), gear fluids mechanism
(for example, gear compressor or gear expanding machine) and Zhuan Gang rolling piston mechanism are (for example, turning cylinder rolling piston compressor or turning cylinder
Rolling piston expander) etc..The displacement type becomes boundary's hydraulic mechanism and is selectively chosen including cylinder, slider and cylinder inward turning
Swivel, and the mechanism that volume changes is complemented each other to form by the cylinder, the slider and the cylinder inner rotary body three.
In the present invention, necessary component, list should be set in necessary place according to the well-known technique of thermal energy and dynamic field
Member or system etc..
Beneficial effects of the present invention are as follows: disclosed in this invention three structure one eccentric shafts in identical weight, same volume
The space that more wobbler actions can be formed under the premise of product becomes in boundary's hydraulic mechanism in displacement type using presently disclosed
Three structure one eccentric shafts can effectively improve the work volume of unit volume and Unit Weight, and then improve efficiency.
