Abstract: Scroll members for scroll compressors made from one or more near-net shaped powder metal processes, either wholly or partially fabricated together from sections. In certain variations, the involute scroll portion of the scroll member has a modified terminal end region. The terminal end region may include an as-sintered coupling feature comprising a tip component that forms a contact surface for contacting an opposing scroll member during compressor operation. The tip component can be a tip seal or a tip cap received by the as-sintered coupling feature. The tip cap may be sinter-bonded or otherwise coupled to the terminal end region. In other variations, a terminal end region may comprise a second material including a tribological material that forms a contact surface. Methods of making such scroll members for scroll compressors are also provided.

Abstract: A light-weight, high-strength compressor component is formed via additive manufacturing that has controlled stiffness and/or deflection levels. 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 comprises the lattice structure in the body portion of the light-weight, high-strength compressor component. The lattice structure may be used to globally or locally control stiffness and/or deflection levels of the compressor component. Additive manufacturing provides flexibility in forming compressor components with desirably improved strength-to-weight ratios while exhibiting high levels of control over stiffness and/or deflection. Methods of making such compressor components via additive manufacturing processes are also provided.

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.

Abstract: A compressor according to the present disclosure includes a shell, a main bearing housing disposed within the shell, a driveshaft supported by the main bearing housing, a non-orbiting scroll member coupled to the main bearing housing, and an orbiting scroll member rotatably coupled to the driveshaft and meshingly engaged with the non-orbiting scroll member. The non-orbiting scroll member forms a suction pocket and at least one circumferential groove. The orbiting scroll member forms a lubricant passage that delivers lubricant from a lubricant source directly to at least one of the suction pocket and the at least one circumferential groove.

Abstract: A compressor may include a first scroll, a second scroll and a modulation system. The first scroll may include a first endplate and a first spiral wrap. The second scroll may include a second endplate and a second spiral wrap interleaved with the first spiral wrap and cooperating to form a plurality of working fluid pockets therebetween. The modulation system may include a temperature-responsive displacement member that actuates in response to a temperature within a space rising above a predetermined threshold. Actuation of the displacement member may be controlled to control a capacity of the compressor.
