Description
Technical field
Improve the rotor-type oil pump of oil-feed the present invention relates to a kind of.
Background technology
Rotor-type oil pump is made up of housing, internal rotor, outer rotor and pump cover etc., the recessed gear ratio internal rotor of outer rotor
Tappet number is more one, the nonsynchronous rotation in the same direction of such inner and outer Rotator, and the outline shape curve of rotor is trochoid, rotor tooth
When shape tooth Profile Design must make the rotor go to any angle, can mutually coordinate a contact on the tooth form profile of each tooth of inner and outer Rotator.
In the side cavity of oil input channel, because rotor is disengaged, volume gradually increases, and produces vacuum, and machine oil is inhaled into, and rotor continues
Rotation, machine oil is brought to the side of oil road, at this moment, and rotor just enters engagement, reduces this cavity volume, oil pressure liter
Height, machine oil is extruded between cog and gone out through oil road force feed.So, with the continuous rotation of rotor, machine oil is just constantly inhaled
Enter and extrude.
When the oil suction chamber that machine oil enters in inner and outer rotors from left to right, but the direction of rotation of inner and outer rotors is counterclockwise；
Or machine oil from right to left enter inner and outer rotors in oil suction chamber, but the direction of rotation of inner and outer rotors be it is clockwise, above-mentioned two
Kind of situation can inner and outer rotors the oil of oil suction chamber can be because centrifugal action be thrown toward oil inlet, to oil inlet when running at high speed
The power that low pressure oil has opposite direction is acted on, so as to reduce volumetric efficiency, adds energy consumption.
The content of the invention
The present invention is intended to provide a kind of improve the rotor-type oil pump of oil-feed, the rotor-type oil pump has volumetric efficiency
The relatively low advantage of high, energy consumption.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of improve is provided with oil inlet, oil-out, internal rotor, outer turned on the rotor-type oil pump of oil-feed, including pump case, pump case
Son and pressure limiting valve, machine oil is flowed to the oil suction chamber between internal rotor and outer rotor by oil inlet, between the oil inlet and oil suction chamber
Pump case on be provided with projection gear slope, the gear slope can block internal rotor and outer rotor operating when oil suction chamber in get rid of to oil inlet
Machine oil.
Wherein, the direction of rotation of the internal rotor and outer rotor is counterclockwise, entering between the internal rotor and outer rotor
Oil pocket is located at the left side of oil inlet.
Wherein, the direction of rotation of the internal rotor and outer rotor is clockwise, entering between the internal rotor and outer rotor
Oil pocket is located at the right side of oil inlet.
Preferably, oil storage tank is provided between the gear slope and inner and outer rotors.
Preferably, the gear slope is inverted v-shaped.
Preferably, the gear slope is the trapezoidal of the narrow lower bottom width in upper bottom.
Preferably, the buffering right angle platform of projection is set on the pump case of the oil inlet side, and the drain tap of pressure limiting valve is set
Above oil inlet, the machine oil flowed out in the drain tap falls on buffering right angle platform, then flows into oil inlet.
Wherein, the oil-out is located at the surface of oil inlet.
The invention has the advantages that：
By being provided with the gear slope of projection on the pump case between oil inlet and oil suction chamber, gear slope can block internal rotor and outer rotor
The machine oil to oil inlet is got rid of during operating in oil suction chamber, the oil-feed situation of oil inlet can be improved, it is relatively low with volumetric efficiency height, energy consumption
Advantage, and parts need not be increased, manufacturability and processing cost are low.
Brief description of the drawings
