  • Patent number: 7367427
    Abstract: A lubrication system for supplying lubricants between two environments is provided. The first environment is disposed within a first housing and the second environment is disposed within a second housing having a supply opening and an exhaust opening. The system includes a lubricant supply tube disposed within the supply opening and configured to supply lubricant from the first environment to the second environment. The system also includes a receptacle disposed within the second housing and configured to receive lubricant supplied from the supply tube and to hold a predetermined volume of the lubricant. A check valve is disposed within the second housing and is in fluid communication with the exhaust opening. The check valve is configured to receive overflow lubricant from the receptacle, if the lubricant exceeds the predetermined volume and to provide a seal between the first and second environments in response to a pressure differential therebetween.

  • Patent number: 5980222
    Abstract: A compressor assembly includes a compressor mechanism mounted within a hermetically sealed housing. The housing is effectively divided into a low pressure area at a relatively low temperature and a high pressure area at a relatively high temperature. A motor and a lubrication system are contained within the low pressure area and the discharge side of the compressor mechanism is disposed in the high pressure area. A cylinder block effectively separates the high and low pressure areas of the compressor. The lubrication system includes an axial passage for communication oil from a sump to various compressor components, including rotational bearings. A seal cap is disposed at the end of the crankshaft that extends into the high pressure area and in combination with the cylinder block defines an oil discharge chamber at low pressure and isolated from the high pressure area.

  • Patent number: 5836421
    Abstract: A lubricating system for an internal combustion engine maintains lubrication even in extreme emergency positions of the engine such as slants within the range of about 90.degree. to about 270.degree., relative to the horizontal and even for upside down engine positions. For this purpose, a hydraulic accumulator (16) is connected to the lubricant circulating circuit through a parallel connection of a non-return valve (17) and a controllable valve. Under normal operating conditions, the hydraulic accumulator is charged with lubricant under the pressure prevailing in the lubricant circulating system. Under emergency conditions, the normal lubrication is stopped and emergency lubrication continues through the controllable valve that is opened in response to a pressure drop in the normal lubricant circulating system.

  • Patent number: 5782616
    Abstract: The present invention relates to an oil pump of the forced lubrication system in an automobile engine. The oil pump is mounted in the lower crank case, preferably at the bottom of the oil pan in order to be immersed in a lubricating oil filled therein. The oil pump of the present invention is a combination of the well known plunger type oil pump and the swash-plate pump, which has two pistons and one T-shaped operating rod incorporated therein. The outer end of the T-shaped operating rod is extended to the engine crank shaft. The outer end of the operating rod is directly coupled to the bearing load of the crank shaft, opposite to the engine connecting rod, to form a second connecting rod which allows translation of the connecting rod from rotation of the crank shaft.

  • Patent number: 5377781
    Abstract: An oil pick-up device of a refrigeration compressor. This device includes an oil pick-up tube for raising a refrigeration oil to a drive part of the compressor. The oil pick-up tube has an annular protrusion for scattering the refrigeration oil ascending an outer surface of the tube and restricting generation of oil foams. The tube also has an air exhaust port for exhausting air bubbles and foreign substances of the refrigeration oil ascending the inside of the tube. This oil pick-up device efficiently scatters refrigeration oil while restricting the generation of oil foams, exhausts air bubbles as well as foreign substances from the refrigeration oil and prevents the generation of a pressure differential to reduce noise.

  • Patent number: 4920876
    Abstract: A refuse compactor includes a refuse container housing an upright compaction ram actuated by a vertically oriented scissors mechanism. The scissors mechanism is actuated by vertical movement of a horizontal crossbar connected to one set of scissors arms. The crossbar is moved by a vertically suspended ball screw acting on a ball nut floatingly connected to the cross bar. The ball screw is suspended at its upper, driven end in thrust bearings while its lower end is unrestrained. An oiler automatically oils the ball screw upon each inversion and return of the container to an upright condition in dumping refuse. An automatic ram cycler periodically extends and retracts the ram to prevent it and the compacted refuse in the container from freezing to the container when ambient air temperatures drop below freezing.

  • Patent number: 4433655
    Abstract: A pump supplies pressurized lubricant to an internal combustion engine from an external reservoir through a closed loop system. Delivery channels extending through the crankshaft, connecting rod and other components, supply the pressurized lubricant to the several areas of relative movement. Return channels, extending through the components, conduct lubricant from the several areas to the reservoir. Fuel-air mixture from a carburetor enters the crankcase through the open end of the crankshaft and moves through ports within the several cylinders to the respective combustion chambers. Selected ports are sequentially closed by a valve plate carried by the crankshaft. Incomplete products of combustion are exhausted into an auxiliary exhaust outlet for recycling with the fuel-air mixture. Retainer members engaging the spark plugs assist in dissipating heat therefrom.

  • Patent number: 4050544
    Abstract: A lubrication system for an air motor which incorporates a positive feed oil pump, driven by the air motor, which forces lubricant, under pressure to the majority of critical lubrication zones. Because of manufacturing tolerances as well as ease of maintenance, the rotary valve and the main crankshaft are coaxial but separate. The lubricant is forced inwardly to the axis of either the crankshaft or the rotary valve and then transmitted to the other rotating member by way of a hollow elastic snubber which preloads the valve and crankshaft in opposite directions.

  • Patent number: 3983958
    Abstract: Apparatus is provided for attachment to a bearing housing through an access conduit, which provides means for allowing observation of the lubricating oil in the bearing housing, ascertaining the level of oil in the lubricating housing, and maintaining a desired fluid level in the bearing. The apparatus provided has an upper chamber and lower chamber, separated by a partition. An opening in the partition allows fluid communication between the upper and lower chambers with a tube connected to the opening and extending a distance into the lower chamber. An aperture through the housing in the lower chamber above the lower end of the tube allows ambient pressure in the lower chamber. Lubricating oil in the two chambers may be pushed from the chambers through the access conduit by a plunger in the upper chamber when the aperture is covered by the hand to remove any blockage of the conduit and then upon withdrawal of the plunger bringing fluid back into the lower and upper chamber.
