Abstract
The invention discloses an engine oil pump, which comprises a engine oil inlet 1, a pump body 2 and an oil outlet 3, wherein an ejector pipe 4 for supplementing flow capacity of the inlet of the oil pump is arranged on a pipe of the engine oil inlet 1 and is connected with an engine lubricating oil channel, as a result, the flow capacity and the efficiency of the engine oil pump are improved, the engine can be reliably lubricated, and the normal operation of the engine is ensured.
Description
Technical field
The invention belongs to the oil pump field, be specifically related to a kind of oil pump for engine lubrication system.
Background technique
Engine oil pump is the important component part of lubrication system, and its effect is continuously to force fuel feeding to each friction surface, and motor is lubricated reliably, reduces the friction and wear of part, for the normal operation of motor provides safeguard.
Lubricant oil enters oil pump by the oil pump import, after pressurization, enters engine interior by the oil pump oil outlet in oil pump, and each load parts are lubricated with cooling.
Application number a kind of oil pump that has been 201010562684.6 Patent Application Publication, comprise oil pump trap, the oil pump cover plate that is connected with the oil pump trap, with the fixing oil pump body of oil pump cover plate, be arranged at the oil pump location dowel on the oil pump body, the sprocket wheel that is connected with oil pump body opposite side and the chain housing of being located at the sprocket wheel opposite side, be provided with on the oil pump body and control oil duct and the second pressure-limit valve, control oil duct and be connected with the engine lubrication system main oil gallery, the second pressure-limit valve is arranged to be controlled in oil duct.The engine oil pressure level that the second pressure-limit valve can guarantee each friction pair of motor main oil gallery in the reasonable scope.This invention is simple in structure, application is convenient, can prevent effectively that engine oil pressure too high in main oil gallery is on the impact of each parts of motor.
Motor is larger to the demand of flow of lubrication, and is higher to the oil transportation Capability Requirement of oil pump.For the certain oil pump of size, the flow during rated speed is larger, and the oil transportation ability of oil pump is stronger, can satisfy the higher demand of motor.
Summary of the invention
For improving the supply capability of oil pump, the invention provides a kind of oil pump with the import induction tunnel.
Technological scheme of the present invention is:
A kind of oil pump comprises machine oil import 1, and the pump housing 2 and oil outlet 3 are provided with the induction tunnel 4 that replenishes the oil pump inlet flow rate on the pipeline of machine oil import 1, and induction tunnel 4 is connected with the engine lubrication oil duct.
Beneficial effect of the present invention: by the induction tunnel that is connected with the engine lubrication oil duct in oil pump import setting, the effectively flow of lift oil pump and efficient make engine reliable lubricated, for the normal operation of motor provides safeguard.

Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
The first embodiment:
A kind of oil pump comprises machine oil import 1, and the pump housing 2 and oil outlet 3 are provided with on the pipeline of machine oil import 1 and replenish oil pump inlet flow rate induction tunnel 4, and induction tunnel 4 is connected with the engine lubrication oil duct.
In the present embodiment, oil pump import induction tunnel 4 is connected with the engine lubrication oil duct, the lubricant oil with certain pressure in the engine lubrication oil duct can be got back to oil pump import 1 by induction tunnel 4, lift oil pump inlet pressure, oil pump efficient is improved, increase oil pump capacity, lift oil pump feed ability.
Machine oil import 1 angle at 45 ° of preferred induction tunnel 4 and oil pump can increase the ejector capacity of induction tunnel, effectively the lift oil pump flow.
The second embodiment:
A kind of oil pump comprises machine oil import 1, and the pump housing 2 and oil outlet 3 are provided with on the pipeline of machine oil import 1 and replenish oil pump inlet flow rate induction tunnel 4, are provided with drainage tube 5 on the pipeline of oil outlet 3, and induction tunnel 4 is connected with drainage tube and is connected by pipeline.
In the present embodiment, oil pump import induction tunnel 4 is connected by pipeline with drainage tube 5, and inlet pressure that equally can the lift oil pump is avoided simultaneously being connected to the engine lubricating oil deferent and passed by long problem.
Preferred induction tunnel 4 is connected with drainage tube and is connected by rubber hose, draws materials conveniently, and is cheap, avoids other positions interference of connecting tube and motor.
