A lubrication system includes an engine oil pump, a lubricating oil tank, a breathing pipe, a machine body, and an oil pan. The engine oil pump is formed by superposing upper and lower layers being a lubricating pump and an oil return pump. An oil inlet of the oil return pump leads to a cavity of the oil pan, and an oil outlet leads to an interior of the lubricating oil tank. An oil inlet of the lubricating pump leads to the interior of the lubricating oil tank, and an oil outlet leads to a machine filter. The machine filter is communicated with a main oil path of the machine body. An oil tank cover of the lubricating oil tank is provided with a breathing one-way valve and an oil filling port. The breathing one-way valve communicates one end of the breathing pipe, and the other end thereof communicates a crankcase.

There is disclosed a lubricant debris monitoring system for a gas turbine engine. The system includes a magnetic chip collector having electrodes defining a gap therebetween configured to be filled with lubricant. The magnetic chip collector generates a magnetic field for attracting the debris. The system further includes a processor configured to be connected to a power source and for performing an analysis of an signal between the electrodes. The processor stores occurrences of at least one characteristic of the signal exceeding a respective threshold. The system further has a communication system communicatively connected to the processor and configured for transmitting the analysis of the signal.

Module (60) for attracting and detecting ferromagnetic debris in an oil flow from a turbomachine, the module (60) comprising: a permanent magnet (62); a bar (64), the bottom (66) of which extends radially and is wound around a coil (70). The coil (70) is able to detect the magnetic field generated by the magnet (62) and in particular its variations when a ferromagnetic particle comes into the vicinity of the magnet (62).

An apparatus facilitates multiple paths or circuits through an engine and remote housing for an oil filter. The apparatus includes a first oil filter chamber housing a first oil filter, a second oil filter chamber housing a second oil filter, a first output of the remote housing configured to provide a path from the first oil filter chamber housing to bearings of an engine, a second output of the remote housing configured to provide a path from the second oil filter chamber housing to a sump of the engine, and an input of the remote housing configured to provide a path from an oil pump of the engine to the first oil filter chamber housing.

A magnetic filtration device for installing as a replacement to a standard drain plug commonly positioned at the bottom of the reservoir. The magnetic filtration device may attract and capture magnetic (ferromagnetic) particulate circulating throughout a mechanical system. Applications for the device include engines, motors, pumps, compressors, gear boxes, transmissions, hydraulic systems, and generators. The magnetic filtration device may comprise a magnet core enclosed within a magnet casing, with additional magnetic rods affixed to and/or arranged around the magnet casing.

A grease filter for filtering grease and the use of the grease filter for a bearing in a wind turbine is provided. A grease filter is disclosed for filtering grease used for lubrication. The grease filter includes and inlet to allow the grease to enter the filter and an outlet to allow the grease to leave the filter, whereby the grease flows from the inlet towards the outlet along a flow path. The filter includes at least one magnetic element present in the flow path of the grease to attract magnetic particles present in the grease and deviate the particles out of the grease flow path.

Magnetic chip detectors and associated for detecting metallic chips in engine fluid of an engine are provided. A magnetic chip detector includes first and second magnetic chip capture zones. The first magnetic chip capture zone includes a first electrically conductive terminal spaced apart from a second electrically conductive terminal to define a first chip-receiving gap therebetween. The second magnetic chip capture zone includes a third electrically conductive terminal and either the second electrically conductive terminal or a fourth electrically conductive terminal to define a second chip-receiving gap therebetween. The magnetic chip detector includes an electric circuit including both the first chip-receiving gap and the second chip-receiving gap. The electric circuit provides an output indicative of a chip detection by one or both of the first magnetic chip capture zone and the second magnetic capture zone.

An electric compressor includes a housing and a compression device. The housing defines an intake volume and a discharge volume. The compression device is a rotary-type compression device configured to compress refrigerant. The compression device includes a piston device including a cylinder and a rolling piston. The cylinder is eccentrically coupled to a drive shaft. The rolling piston has an outer surface in contact with an inner surface of a compression chamber. The rolling piston rotates about the cylinder as the drive shaft and the piston device are rotated by a motor. A vane moveably coupled to the housing and having an end adjacent the compression chamber is biased such that the end of the vane is in contact with the rolling piston as the piston device is rotated by the drive shaft.
