Abstract

A climate-control system may include first and second compressors and a suction manifold. The first compressor includes a first shell, a first compression mechanism, and a first suction inlet through which working fluid is drawn into the first compressor. The second compressor includes a second shell, a second compression mechanism, and a second suction inlet through which working fluid is drawn into the second compressor. The suction manifold includes first and second arms. The first arm provides working fluid to the first suction inlet. The second arm provides working fluid to the second suction inlet. The second arm includes a first suction pipe, a second suction pipe, and a suction valve. The suction valve is movable between a first position in which working fluid is allowed to flow through the first suction pipe and a second position in which working fluid is allowed to flow through the second suction pipe.

Abstract

A compressor may include a shell assembly, first and second scrolls, a floating seal assembly, a modulation-valve ring, and a modulation-control-valve assembly. The shell assembly may define a suction-pressure region. The first scroll may include a discharge passage, a modulation port, and a biasing passage. The modulation-valve ring may cooperate with the floating seal assembly and the first scroll to define an axial-biasing chamber in fluid communication with the biasing passage. The modulation-valve ring may be axially displaceable between a closed position to close the modulation port and an open position to open the modulation port. The modulation-control-valve assembly may be mounted to the modulation-valve ring and may be movable between a first position corresponding to the closed position and a second position corresponding to the open position.

Abstract

Scrolls made from injection molding processes are disclosed. The scroll components have a tip seal groove defined within an involute portion of the scroll. Bearing and tip seal engaging plates are integrally molded within base members of the scroll.

Abstract

A connector block assembly has a connector block and a plurality of end fittings which are attached to at least one wire. Each end fitting is secured to the connector block by being inserted into the connector block and then being rotated to trap the end fitting within the connector pin. Once assembled onto a conductor pin, the conductor pin prohibits rotation of the end fitting with respect to the connector block and thus the disassembly of the end fitting from the connector block.
