International Classification:

F04B 3900

US Classification:

417312, 181256, 181257

Abstract:

A reciprocating piston compressor having a suction muffler and a pair of discharge mufflers to attenuate noise created by the primary pumping frequency in the primary pumping pulse. The suction muffler is disposed along a suction tube extending between the motor cap and the cylinder head of the compressor. The discharge mufflers are positioned in series within the compressor to receive discharge gases from the compression mechanism and are spaced one quarter of a wavelength from each other so as to sequentially diminish the problematic or noisy frequencies created during compressor operation. The motor/compressor assembly including the motor and compression mechanism is mounted to the interior surface of the compressor housing by spring mounts. These mounted are secured to the housing to define the position of the nodes and anti-nodes of the frequency created in the housing to reduce noise produced by natural frequencies during compressor operation.

Inventors:

Dan Manole - Tecumseh MI, US
Phillip Tomell - Adrian MI, US

Assignee:

TECUMSEH PRODUCTS COMPANY - Tecumseh MI

International Classification:

F04B 35/04

US Classification:

417417000

Abstract:

A linear compressor that is operated at a frequency greater than the natural frequency of the spring-mass system of the compressor. Operating the compressor at such a frequency can increase the output of the compressor. In one embodiment, the linear compressor includes a cylinder block having a cylinder bore, a piston positioned within the cylinder bore, first and second springs for positioning the piston where the piston and the first and second springs comprise the spring-mass system, and an armature operably engaged with the piston to drive the piston at a frequency greater than the natural frequency of the spring-mass system. The linear compressor can also include a controller which monitors the instantaneous natural frequency of the spring-mass system and modulates the frequency of the current passing through the armature such that it exceeds the natural frequency of the spring-mass system.

International Classification:

B65D 90/32

US Classification:

220 891

Abstract:

A hermetically sealed compressor including a pressure release device. In one exemplary embodiment, the pressure release device includes a flange portion and a rupture portion. The flange portion is positioned against and secured to the inner surface of the housing of a hermetically sealed compressor. In this embodiment, the rupture portion extends at least partially within a vent aperture extending through the compressor housing. When the interior pressure of the housing exceeds a predetermined limit, the rupture portion of the pressure release device opens allowing the fluid within the compressor housing to escape. In another exemplary embodiment, the pressure release device further includes a connecting portion positioned between the flange portion and the rupture portion. In one exemplary embodiment, the connecting portion forms an S-curve.

Abstract:

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.
