The second cap may be received within the second end and may include a second side wall having a second groove. The first snap ring may be disposed within the first groove and may engage the first end to restrict removal of the first cap from the body.

| An electric compressor includes an inverter housing accommodating an inverter, a compressor housing accommodating a compression mechanism and an electric motor, and a seal member having an annular shape and interposed between an end surface of a peripheral wall of the compressor housing and an end surface of the inverter housing. The compressor housing has the peripheral wall in which the inverter is disposed. The seal member is retained to the inverter housing by a retaining structure which is disposed inside the peripheral wall of the compressor housing. The retaining structure includes a first projection and a second projection. The first projection is formed on the seal member and projects radially inward. The second projection is formed on the inverter housing. The first projection is located between the second projection and the end surface of the inverter housing so as to restrict movement of the seal member in a direction. | ||||||
| 103 | SEALING JOINT FOR A COMPRESSOR CASING | US14413163 | 2013-07-08 | US20150198170A1 | 2015-07-16 | Mark W. Harrison |
| A sealing joint for a compressor casing, such as a compressor casing for a centrifugal compressor of a chiller, is provided. The sealing joint may be configured to have a first cover and a second cover. A first mating surface of the first cover may have an inner annular portion surrounding an inner cavity of the sealing joint, and an outer annular portion. The inner annular portion may be positioned between the inner cavity of the compressor casing and the outer annular portion. A sealant may be applied to the sealing joint, and a depth of the sealant on the inner annular portion may be deeper than a depth of the sealant on the outer annular portion. The depth of the sealant on the inner annular portion may help the sealing joint tolerate more elongation range without a sealant failure than a regular casing. | ||||||
| 104 | Scroll Pump Having Axially Compliant Spring Element | US14102943 | 2013-12-11 | US20150159650A1 | 2015-06-11 | Ronald J. Forni |
| A scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a non-energized type of tip seal or seals, an eccentric drive mechanism assembled to and supported by the frame and to which the orbiting plate scroll is assembled so as to be drivable by the eccentric drive mechanism in an orbit about a longitudinal axis of the pump, and an axial compliance system including a flexure. The flexure is interposed between a bearing of the eccentric drive mechanism and a flexure-locating surface of the eccentric drive mechanism. The flexure allows the orbiting plate scroll to move away from the stationary plate scroll in the case of an assembly process which would otherwise result in the tip seal(s) being too forcefully engaged with the plate of the opposing plate scroll. | ||||||

| A scroll compressor includes a compression mechanism including fixed and movable scrolls. The fixed and movable scrolls have end plates and spiral laps. The laps are engaged to form a compression chamber. The end plates are in pressure contact around the compression chamber to form a thrust sliding surface. The thrust sliding surface has an oil groove extending around the compression chamber. High-pressure refrigerating machine oil is supplied to the oil groove. During orbiting of the orbiting scroll, at least in a region serving as a suction space of fluid in an outer peripheral portion of the compression chamber, an outer seal length from an outer peripheral edge of the oil groove in the thrust sliding surface to an outer edge of the movable end plate is smaller than an inner seal length from an inner peripheral edge of the oil groove to a peripheral edge of the compression chamber. | ||||||

The seal assembly may surround the discharge passage and fluidly separate the first and second pressure regions from each other. The seal assembly may include first and second sealing members. The first sealing member may prevent communication between the chamber and the second pressure region when a first fluid pressure within the second pressure region is higher than a second fluid pressure within the chamber. The first sealing member may define a leakage path when the first fluid pressure is lower than the second fluid pressure. The second sealing member may fluidly separate the chamber and the second pressure region when the first fluid pressure is lower than the second fluid pressure. | ||||||
