Description
Technical field
The present invention relates to a kind of pump covers of lubricating oil pump, and in particular to a kind of pump cover that can install safety valve.
Background technology
At present, lubricating oil pump is pumped as the conveying of the lubricating oil of engine, at work, can generate larger pressure,
It can cause to pump that interior pressure is excessive due to various reasons, to prevent excessive pressure from causing the damage of the pump housing and causing other things
Therefore safety valve is usually all installed on the pump housing, when pressure is excessive in pump, safety valve is opened, and the machine oil in pump passes through safety valve
Discharge, current safety valve is typically separately fabricated, is then mounted on the pump housing again, causes the complicated of lubricating oil pump, ties up
Shield is inconvenient.
Invention content
To solve the above problems, the present invention proposes a kind of pump cover, whole installation is useful for assembling safety valve on the pump cover
Valve opening, to reduce the complexity of lubricating oil pump, specific technical solution is as follows：
A kind of pump cover that can install safety valve, the pump cover are included in flat ontology, which includes one for covering
The inner surface being located on the pump housing is provided with axis hole, oil outlet on ontology, which runs through the ontology, in the interior table of ontology
Face is provided with oil suction chamber and oil outlet chamber, and oil suction chamber and oil outlet chamber are positioned opposite；In the side vertical with above-mentioned inner surface of ontology
Safety valve body is provided with, which is integrally formed with ontology, and spring mounting hole, spring installation are offered in safety valve body
Safety valve body is stretched out in the one end in hole, and the other end of spring mounting hole extends into the ontology and is formed continuously valve ball section and import
Section, spring mounting hole, valve ball section and inducer form the cavity for installing safety valve component；The oil outlet passes through oil outlet chamber
It is connected with inducer；The oil leak hole for leading to body exterior is provided in valve ball section.
Further, the oil outlet is perpendicular to the axis hole.
Further, the oil outlet is perpendicular to the safe valve opening.
Further, the diameter of the valve ball section is more than the diameter of inducer, and less than the diameter of spring mounting hole.
Further, the pin hole of the safety valve body is provided through in the one end of safety valve body far from ontology.
The present invention is provided with safety valve body on the ontology of pump cover, for installing the cavity of safety valve component from safety valve body
It extend into ontology always, and outlet opening is made to connect the inducer of cavity again after passing through oil outlet chamber, to reduce the volume of pump cover, by
It is integrally formed in ontology in safety valve body, when avoiding using split structure, not only the mounting surface of equipment is more, and makes group
Component into safety valve is not easy to position in installation process, and safety valve may be caused to open or postpone the accident opened in advance.
Description of the drawings

Offer spring mounting hole 16 in valve body, safety valve body is stretched out in one end of spring mounting hole, and the other end of spring mounting hole is to institute
It states and extends in ontology and be formed continuously valve ball section 22 and inducer 21, spring mounting hole 16, valve ball section 22 and inducer 21 are formed
For installing the cavity of safety valve component；The oil outlet is connected across oil outlet chamber 11 with inducer 21；It is set in valve ball section 22
There is the oil leak hole 17 for leading to body exterior.
In the present embodiment, the oil outlet 13 is perpendicular to the axis hole 19.Oil outlet 13 is perpendicular to the safe valve opening
16.The diameter of valve ball section 22 is more than the diameter of inducer 21, and less than the diameter of spring mounting hole 16.In safety valve body far from this
One end of body is provided through the pin hole 23 of the safety valve body.
The mounting hole 12 for installing the lubricating oil pump with above-mentioned pump cover is provided in the both sides of oil leak hole.
