摘要： A lubrication assembly for supplying pressurized lubricant to the center bearing of an exhaust-driven turbocharger associated with an internal combustion engine during turbocharger spin down after the engine has been shut down comprises a reservoir means for storing a quantity of lubricant under pressure. The reservoir means is coupled in fluid communication with the lubricant line which supplies lubricant to the center bearing when the engine is running. A valve means controls flow of lubricant between the center bearing lubricant line and the reservoir means. This valve means permits the reservoir means to capture and store lubricant at peak engine lubricant pressure. The valve means releases lubricant from the reservoir means to the center bearing in order to provide lubricant to the center bearing during the turbocharger spin down period after engine shut down when the engine lubricant pump is likewise shut down. The preferred valve means is a diaphragm type bi-directional valve which is solenoid actuated.

摘要： An oil cooler system for a motor vehicle with a turbo charger has an oil circuit which is constituted by a first oil circuit connecting an oil pan, an oil pump, an oil filter, an oil cooler, a turbo charger and the oil pan in that order. A second oil circuit connects the oil pan, the oil pump, the oil filter, a cylinder block of an engine and the oil pan in that order, providing an oil cooler of the partial-flow type (in which, after passage through the oil cooler, the oil is returned to the oil pan through the turbo charger alone). Since the oil which has been cooled through the oil cooler is sent directly to the turbo charger, the oil temperature at the inlet of the turbo charger is effectively lowered.

摘要： This relates to improvements in turbochargers and more particularly to the venting of the bearing housing of a turbocharger adjacent the compressor housing. Under certain operating conditions, insufficient air is available for the compressor intake, with the result that the compressor draws a vacuum within the compressor housing and causes an undesirable flow of lubricant from the turbocharger bearings to the compressor discharge. This vacuum is applied to the interior of the bearing housing in the general area of the oil deflector and thrust bearing. A vent passage is formed through the oil deflector and the thrust bearing and down between the thrust bearing and bearing support so as to vent that portion of the bearing housing to the lubricant drain cavity, and thereby inhibit undesirable lubricant flow to the compressor discharge.
摘要翻译：这涉及涡轮增压器的改进，更具体地涉及涡轮增压器的与压缩机壳体相邻的轴承壳体的排气。在某些操作条件下，压缩机进气口空气不足，结果是压缩机在压缩机壳体内吸入真空，并导致润滑剂从涡轮增压器轴承流到压缩机排放物。在导油板和推力轴承的一般区域内，该真空被施加到轴承箱的内部。通过导油板和推力轴承和止推轴承与轴承座之间形成通气通道，以将轴承壳体的该部分排放到润滑剂排出腔，从而阻止不期望的润滑剂流向压缩机排气口。

摘要： The impeller bearings in a turbocharger on an internal combustion engine are supplied with a coolant, in the form of lubricating oil from the engine's crankcase, during post-shutdown coasting of the impeller. This coolant is supplied by an accumulator including a piston having an upstream side which is subjected to oil under pressure from the crankcase during engine operation to move the piston downstream for loading a spring affixed to the downstream side of the piston. Coolant leaking downstream of the piston is returned to the crankcase through a valve seat which is closed during engine operation by a valve extending from the downstream side of the piston.

摘要： Disclosed is a combination of a spark ignition internal combustion engine and an exhaust gas driven turbocharger whose compressor component delivers charge air to the air induction system of the engine downstream of the engine carburetor and air cleaner. A tube provides communication between the crankcase of the engine and the impeller shaft bearing housing of the turbocharger compressor component to thereby permit entry of crankcase gases into the bearing housing thereby eliminating the ingestion of bearing lubricating oil along the impeller shaft and through the impeller shaft bearing into the compressor discharge passage when a vacuum condition exits in the compressor component as for example under engine idle condition.

摘要： A supercharger is provided with: a housing; a rotary shaft that is supported inside the housing to be freely rotatable; a compressor wheel that is provided at one end in an axial direction of the rotary shaft; a cooling water supplying pipe and a cooling water discharging pipe that have a flange part at an end and are connected to the housing; and a lubricant supplying pipe that has a flange part at an end and is connected to the housing. The ends of the cooling water supplying pipe and the cooling water discharging pipe are inserted into a cooling water supplying flow path and a cooling water discharging flow path of the housing, respectively. The end of the lubricant supplying pipe is inserted into a first supplying flow path of the housing. The flange part presses the flange parts in an insertion direction and is fixed to the housing.
