摘要： 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.

摘要： A single-screw compressor includes a casing, a screw rotor accommodated in the casing, a gate rotor, and a gate rotor supporting member rotatably supporting the gate rotor. The gate rotor includes a plurality of flat-plate-shaped gates formed in a radial pattern and meshing with a helical groove of the screw rotor. Fluid in a compression chamber defined by the screw rotor, the casing and the gates is compressed when the screw rotor is rotated. The gate rotor supporting member includes a gate supporting portion supporting each gate from a back surface side. The gate rotor and the gate rotor supporting member form a gate rotor assembly including a pressure introduction channel configured and arranged to introduce a fluid pressure on a front surface side of each gate into a gap between a back surface of the gate and the gate supporting portion.

摘要： A scroll fluid machine is configured by engaging a fixed scroll and an orbiting scroll having spiral bodies formed on base plates. A seal member is provided between a rear surface of the orbiting scroll and a frame member arranged opposite thereto to divide a rear side chamber into an inner space and an outer space. The inner space inside the seal member is subjected to a pressure substantially corresponding to a discharge pressure, and the outer space is subjected to a pressure lower than that of an inner back pressure chamber to press the orbiting scroll against the fixed scroll. The scroll members are formed such that the width of a groove and the thickness of a tooth of the spiral body formed inside the seal member are larger than those of the spiral body formed outside the seal member.

摘要： A 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. The relationship between the involute surfaces of the spiral wraps of the two scrolls and the dimensions, dimensional tolerance, and assembly standards of the rotation-preventing mechanism are determined so that the median value of an allowable angle of rotation (φ) agrees with an upright position of the orbiting scroll.

摘要： 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).
