  • Publication number: 20080277008
    Abstract: A reed valve having a plurality of tips and associated recesses is provided as a compressor suction valve with each valve tip coacting with a suction port. The recesses are located in the housing structure defining the cylinder of the compressor and are spaced a distance on the order of 0.1 inches from the tips when the suction valve is closed. The valve is secured on one side of the cylinder and each tip is located along a line from the center of the cylinder through the center, or axis, of a suction port.

  • Publication number: 20080169157
    Abstract: A system for lubricating a crankshaft lip seal having wear surfaces with a lubricant used with the crankshaft. The system includes a compressor housing portion, wherein the lip seal secured in the compressor housing portion for engagement with the crankshaft and a structure in the compressor housing portion for adequately providing lubricant to the lip seal surfaces. In a preferred embodiment the structure includes a bore having a reservoir for maintaining the lubricant in contact with the lip seal and a manner for controlling the amount of the lubricant in the reservoir.

  • Publication number: 20040113369
    Abstract: A crankshaft for use in a compressor that incorporates a lip seal includes a first material forming the crankshaft, an area on the crankshaft that engages the lip seal, and protection for the crankshaft from wear due to frictional contact with the lip seal. The protection includes a secondary material added to the crankshaft causing a hardened surface of the crankshaft at the area. The protection is preferably in the form of a wear sleeve on the crankshaft. The wear sleeve is formed from a second material which wears less than the first material while in contact with the lip seal and the wear sleeve is formed separate from the crankshaft and removable for replacement.

  • Patent number: 6698232
    Abstract: A compressor oil diversion and collection system used in a compressor having a housing, a crankshaft having shaft seals, refrigerant and a compression device for compressing the refrigerant. The system includes a shaft sealing mechanism that uses a lubricant for preventing compressor refrigerant from leaking out of the compressor housing and has a space where the lubricant collects. A diversion mechanism is deployed for directing excess amounts of said lubricant from the space to a receiver for receiving the excess amounts of said lubricant from the diversion mechanism. The receiver may be in the form of an internal cavity which includes a removable cartridge located in the cavity for collecting the excess amounts of said lubricant, an external collection reservoir or an external drainage tube.

  • Patent number: 6540492
    Abstract: A compressor piston has protrusions which extend upwardly into discharge ports to minimize clearance at the end of the compression stroke. The protrusions fit into circumferentially isolated discharge ports, and each of the ports are associated with reed valves. Preferably a cutout portion is formed into the piston head to allow clearance for movement of the suction valve. The suction valve is positioned on an inner face of a valve plate and the discharge reed valves are positioned on an outer face. The protrusions are preferably frustro-conical.

  • Patent number: 6168248
    Abstract: A containment system for a packaged air conditioning unit is disclosed comprising a base pan, a first unit wrapper, a second unit wrapper, a compressor compartment partition, a condenser compartment partition, and a top cover having an indoor section and an outdoor section. The unit wrappers and the compartment partitions are guided into position during installation by engaging a notch formed on the wrapper or partition with a positioning cleat formed on the base pan. Because the unit wrappers and the partitions firmly abut the base ban throughout their length, these components help to laterally stiffen the base pan.

  • Patent number: 5911563
    Abstract: The invention is a blower assembly for a packaged climate control unit such as a packaged air conditioning or heating unit. An orifice ring for receiving and guiding rotation of a blower wheel of the assembly is made detachable so that the wheel can be inserted into and retrieved from the top of the blower assembly housing. Further, the blower assembly may comprise an improved motor stand having vertically oriented pegs which are received by receptacles formed about the outer surface of the motor. When the assembly is installed in packaged unit having a detachable top section, both the blower wheel and the blower wheel motor can be retrieved from the packaged unit for servicing or replacement without removing the blower assembly housing from the packaged unit.
