A hermetic compressor assembly is disclosed including a motor compressor disposed within a hermetically sealed housing, wherein the housing has an oil sump in the bottom thereof from which oil is drawn to lubricate the compressor mechanism. An electric drive motor includes a vertical rotor having a lower axial end ring with an integrally formed rotor counterweight, whereby turbulence and resulting agitation of the oil in the oil sump is prevented during rotation of the rotor.

Integrally formed counterweight for rotor end ring

The present invention is a vertically upright hermetic compressor for mounting to a horizontal support surface. The compressor comprises a housing with a bottom end having an annular groove, a motor compressor unit operably disposed within the housing, and a mounting boot. The mounting boot is affixed to the housing's bottom end, having a resilient body member engaged with the groove to secure vertically the housing. An adhesive is used to bond the boot to the housing bottom, and adhesive can be used to secure the boot to a horizontal support surface of an appliance.

Compressor mounting apparatus

A mounting boot for mounting a vertical hermetic compressor to a horizontal base, includes a resilient cup-shaped member to receive the bottom end of the compressor housing. A cylindrical inner wall surface of the cup-shaped member frictionally engages the sidewall of the compressor. The bottom end of the compressor housing comprises a plate member having a radially extending flange portion resiliently enveloped by the inner wall surface of the cup-shaped member. The bottom end of the compressor housing is spaced from the bottom wall of the mounting boot, thereby defining an enclosed muffling chamber to suppress noises radiated from the compressor bottom end. The mounting boot is formed with radially extending mounting feet, and passages through which compressor inlet and outlet tubes may extend.

Mounting boot for a hermetic compressor

A hermetically sealed rotary compressor and its method of assembly are disclosed, which compressor and method utilize an end plate having an annular groove on its interior surface and an annular recess on its exterior surface. A securing weld in the centroidal plane of the end plate is provided at the junction of a compressor housing mated with the end plate annular groove.
