Abstract: A magnetic HVIL system for a drive in a transport application includes a Hall effect sensor within at least one housing of the drive that includes terminals and a removable cover. The removable cover includes a magnet having a magnetic field that is detectable by the Hall effect sensor when the removable cover is installed on the housing. The magnetic field of the magnet is not detectable by the Hall effect sensor when the removable cover is removed from the housing. The magnet HVIL system is configured to be operable to enable active operation of the drive when the Hall effect sensor detects the magnetic field of the magnet and is in a closed circuit condition and disable operation of the drive when the Hall effect sensor does not detect the magnetic field of the magnet and is in an open circuit condition.

Abstract: A compressor according to the principles of the present disclosure includes a shell, a compression mechanism, a driveshaft, a drive bearing cavity, and a drive bearing. The compression mechanism is disposed within the shell and includes an orbiting scroll member and a non-orbiting scroll member. The orbiting scroll member includes a baseplate and a tubular portion extending axially from the baseplate. The driveshaft is drivingly engaged with the orbiting scroll member. The drive bearing cavity is disposed between an outer radial surface of the driveshaft and an inner radial surface of the tubular portion of the orbiting scroll member. The baseplate of the orbiting scroll member defines a first discharge passage in fluid communication with the drive bearing cavity. The drive bearing is disposed in the drive bearing cavity and is disposed about the driveshaft adjacent to the first end of the driveshaft.

Abstract: A compressor may include a shell, a non-orbiting scroll, an orbiting scroll, and a discharge valve member. The shell may define a discharge chamber. The non-orbiting scroll may be disposed within the discharge chamber and includes a first end plate and a first spiral wrap extending from the first end plate. The orbiting scroll may be disposed within the discharge chamber and includes a second end plate and a second spiral wrap extending from the second end plate. The first and second spiral wraps mesh with each other to define fluid pockets therebetween. The second end plate includes a discharge passage extending therethrough. The discharge valve member may be attached to the second end plate and may be movable between an open position allowing fluid flow from the discharge passage to the discharge chamber and a closed position restricting fluid flow from the discharge passage to the discharge chamber.

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 discharge valve retainer is manufactured from powder metal using FLC4608, FL4405, FC0205 or FC0208 material. The finisher retainer has a density of approximately 6.8 to 7.6 gm/cc. The retainer is carbonitrided, quenched and tempered to achieve a surface hardness of Rockwell 15N 89-93. The exterior of the retainer is contoured to provide for the non-turbulent flow of pressurized gas around the discharge valve.
