Abstract
The utility model provides a valve spool and a valve spool component of a relief valve. The top of the valve spool is provided with at least two claws, and the top surfaces of the claws are planes. The valve spool component of the relief valve comprises the valve spool and a spring arranged at the bottom of the valve spool. Different from a valve spool with a flat top structure, the valve spool is provided with at least two claws on the top. When the valve spool of the relief valve of an engine oil pump works, vibration noise due to pressure release can be effectively avoided, the top of the claw structure functions in drainage of engine oil, pressure can be effectively released in time, and pressure of a main oil gallery is ensured to be within a normal range.
Description
Technical field
The utility model relates to oil pump Decompression valves technology, relates in particular to a kind of spool and relief valve core assembly.
Background technique
Oil pump is as motor key components and parts, and function is that a certain amount of machine oil is transported to the each friction surface of motor with certain pressure, to ensure normal working of engine.Taking common rotor-type oil pump as example, the part mainly comprising is oil pump casing, inner and outer rotors, oil pump relief valve core and Decompression valves spring etc.The effect of oil pump relief valve core is excessive for preventing main oil gallery pressure, and a machine oil part that flows into main oil gallery is leaked into filler opening place, plays pressure release effect, ensures that main oil gallery pressure is in normal range (NR).
As shown in Figure 1, in prior art, the spool 1 in described oil pump relief valve core assembly is generally shaped as cylindrical, and head construction is flat-tope structure.The oil pump relief valve core head of this flat-tope structure, in the time that relief valve core works, can produce noise because of disc vibration, affects Engine Quality, and in the time of pressure release, because spool head does not have flow guiding structure, has pressure release hidden danger not in time.
Model utility content
The utility model provides a kind of spool and relief valve core assembly, and to reduce noise, pressure release is timely.
First aspect of the utility model provides a kind of spool, and described spool top is provided with at least two pawls, and the end face of described pawl is plane.
Spool as above, at least two described pawls are along the uniform setting of described cylindrical spool end face circumference.
Spool as above, two adjacent pawl bottom arc transition connect.
Spool as above, the cross section of described pawl is fan-shaped plan.
Second aspect of the utility model provides a kind of relief valve core assembly, comprises spool, and is arranged on the spring of described spool bottom, and wherein, described spool top is provided with at least two pawls, and the end face of described pawl is plane.
As shown from the above technical solution, the technological scheme that the utility model provides is different from the spool of existing flat-tope structure, adopt top to be provided with the structure of at least two pawls, in the time that oil pump relief valve core is worked, can effectively avoid the vibrating noise producing because of pressure release, meanwhile, drainage can also be played to machine oil in the top of claw-like structure, pressure release timely and effectively, thus ensure that main oil gallery pressure is in normal range (NR).
Brief description of the drawings
Fig. 1 is the structural representation of oil pump relief valve core assembly in prior art;
The structural representation of the spool that Fig. 2 provides for the embodiment of the present invention one;
The structural representation of the relief valve core assembly that Fig. 3 provides for the embodiment of the present invention two.
Embodiment
The structural representation of the spool that as shown in Figure 2, the embodiment of the present invention one provides.As shown in Figure 2, described spool 20 tops are provided with at least two pawls 21, and the end face of described pawl 21 is plane.
The present embodiment adopts top to be provided with the structure of at least two pawls, in the time that oil pump relief valve core is worked, can effectively avoid the vibrating noise producing because of pressure release, simultaneously, drainage can also be played to machine oil in the top of claw-like structure, pressure release timely and effectively, thus ensure that main oil gallery pressure is in normal range (NR).
Further, as shown in Figure 2, described at least two pawls 21 are along the uniform setting of described cylindrical spool 20 end face circumference.
Further, as shown in Figure 2, two adjacent pawl 21 bottom arc transition connect.Can improve the rigidity of each pawl by the design of arc transition; Or the pawl on described spool also can be structure as a whole with described spool, also can effectively improve the rigidity of each pawl.
Particularly, the cross section of described pawl can be fan-shaped plan, directly existing spool is carried out to cutting process, and then forms the claw-like structure shown in Fig. 2.
The structural representation of the relief valve core assembly that as shown in Figure 3, the embodiment of the present invention two provides.As shown in Figure 3, the relief valve core assembly described in the embodiment of the present invention two comprises: spool 20 and be arranged on the spring 30 of described spool 20 bottoms.Wherein, described spool 20 tops are provided with at least two pawls 21, and the end face of described pawl 21 is plane.Particularly, the described spool that the spool described in the present embodiment two can adopt above-described embodiment one to provide, specific implementation structure can, referring to the content in embodiment one, repeat no more herein.
The present embodiment has adopted top to be provided with the structure of at least two pawls, in the time that oil pump relief valve core is worked, can effectively avoid the vibrating noise producing because of pressure release, simultaneously, drainage can also be played to machine oil in the top of claw-like structure, pressure release timely and effectively, thus ensure that main oil gallery pressure is in normal range (NR).
In the above-described embodiments, each embodiment's description is all emphasized particularly on different fields, in certain embodiment, there is no the part of detailed description, can be referring to other embodiments' associated description.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or some or all of technical characteristics is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment's technological scheme of the utility model.
