Horizontal compressor end cap
View Patent ↗A substantially horizontal compressor including a housing having a main body portion with an open end. An end cap is secured to the main body portion with the end cap being provided with a plurality of apertures. The hermetic terminal body of the compressor is sealably fitted into one of the plurality of apertures located in the end cap. One of the apertures is sealably fitted with a heater well in which a substantially cylindrical heater element is removably received. A third aperture may be provided in the end cap in which a sight glass is sealably secured for checking the oil level in the oil sump. An indentation is formed in the end cap to increase the rigidity of the end cap. The proximity of the terminal assembly and heater well allows the wiring therefor to be part of the same wiring harness.
1. A method of assembling a housing for a substantially horizontal compressor, comprising:
mounting a motor in a main body portion of the housing;
forming a plurality of apertures in an end cap;
mounting a terminal assembly and a transparent member in respective ones of the plurality of apertures;
providing a projection on the end cap, the projection having an internal volume defining a heater well;
securing the end cap to the main body portion of the housing wherein the projection extends into the housing and the heater well is accessible from a position exterior to the housing and wherein the housing and end cap form a hermetically sealed enclosure; and
removably disposing a heater element in the heater well.
2. The method of claim 1 , further comprising securing a fence to an outer surface of the end cap wherein the fence surrounds the terminal assembly and heater well.
3. The method of claim 2 , further comprising passing wires electrically connected to the terminal assembly and heater element through an enclosure formed by the fence and a protective cap removeably secured to the fence, the wires electrically connectable to an external power source.
4. The method of claim 2 , further comprising removably securing a protective cap to the fence and positioning an insulative material between the end cap and the protective cap.
5. The method of claim 1 , further comprising forming an indentation in the outer surface of the end cap whereby rigidity of the end cap is enhanced.
