101 COMPRESSOR HAVING SOUND ISOLATION FEATURE EP14865917 2014-11-26 EP3084223A4 2017-08-30 FU WAYNE-CHI; SAUNDERS MICHAEL A; SEIBEL STEPHEN M; GEHRET KEVIN J; STOVER ROBERT C; GILLESPIE PATRICK R
Scroll compressor designs are provided to minimize vibration, sound, and noise transmission. The scroll compressor has a bearing housing, and orbiting and non-orbiting scroll members. The non-orbiting scroll member has a radially extending flanged portion with at least one aperture substantially aligned with the axially extending bore. At least one fastener is disposed within the aperture and the bore. A sound isolation member contacts at least one of the non-orbiting scroll member, the fastener, or the bearing housing, to reduce or eliminate noise transmission. The sound isolation member may be formed of a polymeric composite having an acoustic impedance value greater than the surrounding materials. The sound isolation member may be an annular washer, an O-ring, or a biasing member, by way of non-limiting example. In other variations, fluid passages are provided within the fastener and/or bearing housing to facilitate entry of lubricant oil to further dampen sound and noise.

The present invention provides a screw compressor that can reduce leakage on the high pressure side and reduce the thrust load. A screw compressor (1) comprises a screw rotor (2, 52) and a plurality of gate rotors (5a, 5b, 5c, 5d) . The screw rotor (2, 52) has helical grooves (11a, 11b) in its outer circumferential surface, and is rotatable. In the gate rotors (5a, 5b, 5c, 5d) , a plurality of teeth (12) that meshes with the grooves (11a, 11b) of the screw rotor (2, 52) is radially disposed. The helical grooves (11a, 11b ) comprise: a first screw groove (11a), which compresses a fluid from one end side of the screw rotor (2, 52) to an other end side of the screw rotor (2, 52); and a second screw groove (11b) , which compresses the fluid from the other end side of the screw rotor (2, 52) to the one end side of the screw rotor (2, 52).

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 present invention provides a screw compressor wherein, even if a gate rotor flexes owing to a temperature differential between a casing and a screw rotor during operation of a compressor, the gate rotor is prevented, with a simple configuration, from biting into the screw rotor, which reduces the amount of wear of the gate rotor and prevents a decline in the compressor's performance. The gate rotor (3) comprises a gate rotor main body (30) and a shaft (40) to which the gate rotor main body (30) is attached. An elastic body (5) is disposed between (S) the axle (41) of the shaft (40) and the hole (32) of the gate rotor main body (30).

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.
