The utility model has the advantages that: the oil guide groove is formed in at least one end face of the variable sliding block, so that oil leaked from the end face of the variable sliding block can be introduced into the oil inlet cavity through the oil guide groove, interference of the leaked oil on oil pressure in the variable feedback oil cavity is avoided, and accurate variable is achieved by the variable displacement vane pump.
Description
Technical Field
The utility model relates to an internal-combustion engine lubricating system technical field, especially a variable displacement's vane type oil pump.
Background
In order to separate and seal the variable feedback oil chamber from the oil inlet chamber, a sealing member mounting groove is usually formed on the outer surface of the variable slider, and a sealing support member and a rectangular sealing member are mounted in the groove, and the sealing support member is mounted at the bottom of the sealing member mounting groove and used for supporting the rectangular sealing member.
Pressure oil of a variable feedback oil cavity on an existing vane pump usually comes from a main oil channel, pressure of the pressure oil from the main oil channel is attenuated after the pressure oil is filtered by a machine cooler, so that oil pressure in the variable feedback oil cavity is lower than that of an outlet of the pump, high-pressure oil at the outlet of the pump easily leaks to the variable feedback oil cavity through an end face gap, extra pressure is generated in the variable feedback oil cavity, the extra pressure and the pressure oil from the main oil channel act on a variable slider together to perform variable, and variable inaccuracy occurs, such as the phenomena of not according to expected variable, variable advance and the like.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a prevent vane pump of oil pressure interference, the high-pressure oil of avoiding the pump export passes through the end face clearance seepage to variable feedback oil pocket.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a vane pump of grease proofing pressure interference, includes the pump body, variable slider, variable spring, rectangle sealing strip, is equipped with variable feedback oil pocket between the pump body and variable slider, variable slider is equipped with spring block and sealing member mounting groove, variable spring installs one side of spring block, rectangle sealing strip is installed in the sealing member mounting groove, variable slider is equipped with one at least on a terminal surface and leads the oil groove, the one end of leading the oil groove is located the position that is close to out the oil pocket, and the other end is located the position that is close to into the oil pocket.
In one embodiment, the upper end surface and the lower end surface of the variable slider are respectively provided with an oil guide groove.
In one embodiment, one end of the oil guide groove is located at a position close to the oil outlet cavity, and the other end of the oil guide groove is located at a position close to the oil inlet cavity and the root of the spring pressing block.
Preferably, the oil guide groove is arc-shaped as a whole.
The utility model has the advantages that: the oil guide groove is formed in at least one end face of the variable sliding block, so that oil leaked from the end face of the variable sliding block can be introduced into the oil inlet cavity through the oil guide groove, interference of the leaked oil on oil pressure in the variable feedback oil cavity is avoided, and accurate variable is achieved by the variable displacement vane pump.
