摘要： An output shaft lubricating structure of a liquid pressurizing pump is provided. A first eccentric portion of an output shaft acts as the maximum stress for load when the liquid is pressurized and works. By the power of the output shaft, a telescopic piston of an oil supply device is directly pushed by a second eccentric portion to draw the lubricating oil in a circular core hole and to pressurize and supply the lubricating oil to an oil supply hole of the output shaft to force an oil outlet hole to drain the lubricating oil to the surface of the first eccentric portion for circulatory supplement, such that the turning of a turning wheel on the first eccentric portion can keep better lubrication for a long time so as to prolong the service life of the output shaft and the turning wheel.

摘要： A compressor may include a compression cylinder, a compression piston, a crankshaft, an injection bore, a position sensor, and a valve assembly. The compression piston is disposed within the compression cylinder and is operable to compress a vapor disposed within the compression cylinder from a suction pressure to a discharge pressure. The crankshaft is operable to cycle the compression piston within the compression cylinder. The injection bore may be in fluid communication with the compression cylinder and may be operable to selectively communicate intermediate-pressure vapor at a pressure between the suction pressure and said discharge pressure to the compression cylinder. The position sensor may measure a rotational position of the crankshaft. The valve assembly may be associated with the injection bore. The valve assembly may be operable to control passage of fluid from the injection bore into the compression cylinder in response to data provided by the position sensor.

摘要： A fuel pump includes a holed disk-shaped plate and a coil spring to press the plate toward a lifter. The plate has an inner circumferential surface to be engaged with a groove in a projection-side end portion of a plunger. Also, a joint port that connects the inner peripheral surface of the plate to an outer peripheral surface thereof is provided in the plate. The coil spring is located between the plate and a pump body. The plate is assembled in the fuel pump to dispose the joint port at a position in an opposite direction to the direction of a side force to be generated during compression of the coil spring when viewed from a central axis of the coil spring.

摘要： A high pressure fuel pump includes a plunger, which slidably reciprocates along a slide axis in an inside of a cylinder, a tappet body, which reciprocates integrally with the plunger, and a roller, which is held by the tappet body and is rotated by rotation of a camshaft. When the roller and the cam main body are viewed in a direction of an axis of the camshaft, a contact point, at which the roller and the cam main body contact with each other, is displaced from an intersection point, at which the slide axis of the plunger and a tangent line to a circle of a cross section of the roller at the contact point intersect with each other, in a counter-rotational direction of the cam main body, which is opposite from a rotational direction of the cam main body.

摘要： An exemplary camshaft for a high pressure common rail oil pump and a manufacturing method thereof is provided. The method achieves interference assembly between the mandrel and cam piece, and satisfies anti-rotating torque of the cam piece relative to the mandrel while ensuring the surface hardness of the cam piece. The camshaft includes a mandrel and a cam piece arranged on the mandrel. The anti-rotating torque of the cam piece relative to the mandrel is at least 500 NM after the cam piece and the mandrel are connected by interference fit by hot charge practice. Surface hardness of the cam piece 1 is at least HRC58. The method includes performing interference assembly of the cam piece and the mandrel while performing quenching heat treatment on the cam piece, then quickly cooling the cam piece equipped with the mandrel at the cooling stage during the quenching heat treatment.
