Angle theta, wherein a set of exhaust valve component coordinates with increasing enthalpy hole 22, when the intermediate pressure that increasing enthalpy hole 22 introduces is more than the pressure in cylinder
During power, exhaust valve plate is opened, and when the intermediate pressure that increasing enthalpy hole 22 introduces is smaller than the pressure in cylinder, exhaust valve plate is adjacent to
On valve seat exhaust outlet, prevent the gases at high pressure in cylinder from flowing backwards, the high pressure gas of other set exhaust valve component and high pressure cylinder
Mouth coordinates, which is angular cut, to draw high-pressure refrigerant.
The scope of first angle theta is：0 °~350 °, can be to avoid between delivery valve seat in this angular range, valve seat
The interference that intersects between sliding vane groove.
The center line of increasing enthalpy air inlet section 21 on upper flange 12 is overlooked with the center line of the exhaust valve plate on upper flange 12
There are the second angle δ, the scope of the second angle δ to be for projection on perspective plane：60 °~80 °, in the range of this, middle compacting is cold
Agent can be injected into increasing enthalpy groove 23 by increasing enthalpy hole 22.
The width h of increasing enthalpy groove 23 on upper flange 12 is less than or equal to the diameter phi in increasing enthalpy hole 22, if increasing enthalpy groove 23
Groove width be more than increasing enthalpy hole 22 diameter phi, it is impossible to be effectively connected with increasing enthalpy hole.
3rd angle of the high pressure increasing enthalpy groove 18 of high pressure cylinder and the axis of high pressure cylinderScope be 10 °~90 °, if greatly
In 90 °, refrigerant can be directly impinged on skew wall, produce larger process resistance, or even produces refrigerant reflux, influence to compress
The power consumption of machine.
