Abstract: A sinker equipped with lubrication oil channeling and separating structure is an element of a knitting machine which includes at least a dial, a sinker disc, an oil ejection nozzle to sprinkle lubrication oil and a yarn feeder. The dial includes a plurality of needle troughs to hold respectively a knitting needle. The sinker disc includes a plurality of sinker troughs to hold the sinker. The sinker includes a base located in the sinker troughs, a driving nub located above the base, a knitting portion located at a front end of the base, an oil sprinkling zone interposed between the base and the knitting portion, and a lubrication oil channeling and separating structure interposed between the knitting portion and the oil sprinkling zone. The lubrication oil channeling and separating structure includes a separating slot, a flow channeling portion and an oil blocking portion that are around the separating slot.

Abstract: An oil storing device includes a body portion. The body portion is formed at its one end with an engaging portion having an oil supply port for supplying engine oil and an oil return port for introducing the engine oil. The engaging portion is detachably connected to a connecting portion of a crankcase. Oil storing chambers for storing the engine oil are formed in the body portion so as to be connected to the oil supply port and the oil return port. When the engaging portion is engaged with the connecting portion of the crankcase, the oil supply port is connected to an inlet port leading to an oil pump, and the oil return port is connected to an outlet port to the crankcase.

Abstract: This invention provides a pipe coupling used for changing oil in an engine oil pan with an oil drain port. A drain plug has a drain plug main body having one end to be attached to the oil drain port of the engine oil pan, a recess formed in its outer surface of the other end projecting outward from the oil pan, and an axial oil flow path extending in an axial direction, a valve holder to be arranged in the plug main body, and a valve body held by the valve holder and capable of closing the flow path.

Abstract: The invention relates to a lubrication system for a mechanism (27), on-board a spacecraft. It comprises a non pressurized tank (20) communicating with the mechanism (27) via a tube (220). A piston (23) closes the tube (220) while the mechanism is at rest. The piston (23) is controlled by a first spring (5) and by a second, shape memory, spring (24) opposing the latter, which lengthen by thermal effect. A controller (25, 26) supplies this spring with a current (I) to actuate it. An annular element(7), pushed by a cylindrical spring (6), defines a capillarity filled pumping chamber (22). When the temperature of the shape memory alloy (24) falls back below a threshold, the spring (24) recovers its original shape, the first spring (5) pushes back the piston (23) and expels a dose of lubrication fluid (4).
