| 41 | Scroll compressor having adjustable spacers | US12623520 | 2009-11-23 | US08591210B2 | 2013-11-26 | Clive Frederick Collie |
| A scroll compressor 40 comprises: housing 12, orbiting scroll 26 and fixed scroll 41. The drive shaft 14 has an eccentric shaft portion 18 so that rotation of the eccentric shaft portion imparts an orbiting motion to the orbiting scroll relative to the fixed scroll. Axial spacers 42 are located between the fixed scroll and the housing for spacing the fixed scroll relative to the orbiting scroll. When the scroll compressor 40 is assembled and tested and it is desired to perform shimming, the fixed scroll can be removed and a selected spacer placed in position prior to re-assembling the fixed scroll. | ||||||

| A scroll compressor that suffers no decrease in compression performance due to leakage resulting from a twisting assembly error is provided. This scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll. | ||||||

| Intended is to provide a scroll compressor capable of performing three-dimensional compressions, which can optimize a tip clearance in operation while considering a thermal expansion and a pressure deformation and which can reduce a compression leakage to improve a compression efficiency thereby to realize a high performance. The leading end faces (13c and 13d) and the bottom face of a spiral wrap (13b) have a step portion (13e), and the wrap height on the outer circumference side of the spiral wrap (13b) is made larger than that on the inner circumference side wrap height, so that the scroll compressor can perform three-dimensional compressions capable of compressing in the circumferential direction of the spiral wrap (13b) and in the wrap height direction. The spiral wrap (13b) on the inner circumference side with respect to the step portion (13e) is stepwise or continuously made gradually lower toward the center side of the spiral wrap (13b), and the tip clearance (Δi) of the spiral wrap on the inner circumference side with respect to the step portion (13) is made gradually larger toward the center side of the spiral wrap (13b). | ||||||

The casing includes a discharge port on an inner peripheral surface of the casing. The gate rotor has gates meshing with the helical grooves of the screw rotor to compress gas in compression chambers to discharge the gas from the discharge port after being compressed. The compression chambers are defined by the helical grooves, the casing, and the gates. The discharge port is divided into a first port and a second port when two adjacent helical grooves of the plurality of helical grooves is open to the discharge port as a result of rotation of the screw rotor, with one of the two adjacent helical grooves being open in the first port and the other of the two adjacent helical grooves being open in the second port. | ||||||

| Current piston based air-conditioning system compressors only have isentropic efficiencies near 50%. Making internal leakage and friction negligible, via detailed design of the vane machine, would almost halve power consumption. In addition, by recovering expansion energy that is normally wasted via an expander, the system Coefficient of Performance COP can be improved up to an additional 30%. | ||||||
