Abstract: A light-weight, high-strength insulating compressor component formed via additive manufacturing is provided. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprising the lattice structure minimizes or reduces transmission of at least one of thermal energy, sound, or vibrational energy through the component. Methods of making such compressor components via additive manufacturing processes are also provided.

Abstract: A compressor may include first and second scroll members, first and second bearing housings, and a motor assembly. The first scroll member includes a first end plate and a first spiral wrap extending from the first end plate. The second scroll member includes a second end plate and a second spiral wrap extending from the second end plate and intermeshed with the first spiral wrap to define compression pockets therebetween. The first bearing housing supports the first scroll member for rotation about a first rotational axis. The second bearing housing may support the second scroll member for rotation about a second rotational axis that is parallel to and offset from the first rotational axis. The motor assembly may be disposed axially between the first and second bearing housings and may include a rotor attached to the first scroll member. The rotor may surround the first and second end plates.

Abstract: 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.

Abstract: A compressor may include a first compression member, a second compression member, and a motor assembly. The second compression member is movable relative to the first compression member and cooperates with the first compression member to define a compression pocket therebetween. The motor assembly drives one of the first and second compression members relative to the other one of the first and second compression members. The motor assembly includes a stator and a rotor. The rotor is rotatable relative to the stator about a rotational axis. The stator surrounds the rotational axis. The rotor may include magnets that are arranged around the rotational axis. The magnets may be spaced apart from the stator in an axial direction that is parallel to the first rotational axis.

Abstract: A compressor may include first and second scroll members having first and second scroll wraps, respectively. The scroll members define a suction inlet, a discharge outlet, and fluid pockets moving therebetween. The second scroll member may include a port, and a passage. The port may be in fluid communication with at least one of the pockets. The passage may extend through a portion of the second end plate and may be in fluid communication with the port. A valve assembly may be disposed in the passage and may include a valve member displaceable between open and closed positions. A recompression volume may be disposed between the valve member and the at least one of the pockets. The recompression volume may be less than or equal to approximately one percent of a volume of one of the pockets at a suction seal-off position.

Abstract: A compressor includes a housing, a partition, a first scroll, a second scroll, and a valve assembly disposed within the second scroll. The valve assembly includes a valve housing, a valve body, and a first biasing member configured to displace the valve body from a first position to a second position relative to the valve housing. When in the first position, the valve body inhibits fluid communication between a fluid source and one of a series of compression pockets formed by the first and second scroll. When in the second position, the valve body allows fluid communication between the conduit and one or more of the series of compression pockets. The valve body is displaceable between the first and second positions in response to a change in operating temperature of the compressor.
