| 20090000872 | Compressor - This invention provides a compressor that can efficiently return lubricating oil through an oil storage chamber to a lubrication target site without residence of the lubricating oil within the discharge chamber and can prevent deterioration in lubrication performance. The compressor comprises a housing having a discharge chamber for lubricating oil-containing hydraulic fluid and a discharge port communicating with the discharge chamber, a rotational shaft extended into the housing, a compression unit for the suction, compression and discharge of the hydraulic fluid through the drive of the rotational shaft, and a lubricating oil separator comprising a separation chamber and an oil storage chamber. The separation chamber is provided between the discharge chamber and the discharge port in the housing. The oil storage chamber is located below the separation chamber. Lubricating oil separated from the hydraulic fluid in the separation chamber is introduced through an oil hole is stored in the oil storage chamber. The compressor further comprises a communication section for directly communicating the discharge chamber and the oil storage chamber without through the separation chamber. | 01-01-2009 |
| 20090000873 | Winterized turbocompressor unit and method for winterizing the turbocompressor unit - A winterized turbocompressor unit has a turbocompressor and an oil supply installation for supplying the turbocompressor with a lubricating oil, the lubricating oil being a low-temperature oil and the turbocompressor and the oil supply installation being set up to be operated with the low-temperature oil. | 01-01-2009 |
| 20090095572 | Oil Valve Assembly of Linear Compressor - The present invention discloses an oil supply valve assembly of a linear compressor including a shell, the oil being stored at the lower portion of the shell, a cylinder disposed in the shell, a piston disposed in the cylinder, a main body frame to which the cylinder is fixed, and a linear motor connected to the piston, for driving the piston, comprising: a passage formed in the main body frame, for supplying the oil to a gap between the cylinder and the piston; an oil valve being coupled to the main body frame to communicate with the passage, and including an oil suction valve and an oil discharge valve; and an oil cover coupled to overlap with the oil valve and communicate with the passage of the main body frame. By this configuration, the manufacturing process of the oil supply valve assembly is simplified and mis-assembly of the components is prevented by reducing the number of the components. | 04-16-2009 |
| 20090101442 | HERMETIC COMPRESSOR - The hermetic compressor has grooves provided at an upper side and a lower side of outer circumference of a piston. Of outer shape of the grooves, the outer shape of the grooves communicating with a space in the hermetic container at least when the piston is in a bottom dead center is a shape not forming parallel line to an axial center of the piston when the grooves are developed in a plane. | 04-23-2009 |
| 20100059317 | AUTOMOTIVE TURBOCHARGER WITH INTEGRAL LUBRICATING OIL FILTER - A turbocharger includes a housing, a rotating assembly mounted within the housing, a lubrication passage for admitting lubricating oil into the turbocharger, and a lube oil filter, mounted within a portion of the lubrication passage so that oil entering the turbocharger will pass through the lube oil filter, removing any contaminants arising from the engine's lubrication system. | 03-11-2010 |
| 20160160857 | LIQUID REFRIGERANT PUMPING SYSTEM - A lubricant supply system includes first and second tanks, each including an internal volume that is divided into a first portion and a second portion. The first portion of the internal volume of the first tank and the first portion of the internal volume of the second tank are configured to alternate supplying a liquid refrigerant to a machine. A pump is in fluid communication with the second portion of the internal volume of the first tank and the second portion of the internal volume of the second tank. The pump is configured to vary a pressure of a gas in the second portion of the internal volume of the first tank and the second portion of the internal volume of the second tank. | 06-09-2016 |
| 20160186736 | Check Valve and Method and Apparatus for Extending Life of Check Valve - A device and method are described for extending the life of check valves. An improved check valve having a double poppet and tapered guides is more robust, and a check valve protection device between the check valve and the environment into which fluid is injected protects the valve from a contaminating or corrosive environment. The check valve and check valve protection device are small and light weight to prevent vibration-induced failures. The check valve protection device preferably has an interior volume that fills quickly by relatively few cycles of the lubricant pump to reduce delay of lubricant to the injection point. | 06-30-2016 |
