Description
Technical field
The utility model relates to auto parts and components control valve technical fields, more particularly, to a kind of spool of economizer.
Background technique
Economizer is by changing throttling section or chock length to control the valve of fluid flow, and fuel-economizing spool is fuel-economizing
Important valve body component in valve.Existing fuel-economizing valve core structure is excessively complicated, has clogging, and the flow of oil liquid
It is not sufficiently stable.Therefore, designer improves existing spool.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of valves of the economizer of simple structure and reasonable design
Core.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of spool of economizer, including valve
Core ontology, the insert body is cylindrical, and the side evagination of the insert body has several annulus, two neighboring annulus
Between there are preset space length, annular groove is equipped between two neighboring annulus, the annular groove is equipped with several first oilholes, institute
Several first oilholes interval predetermined angular stated circumferentially is arranged, is equipped in the insert body and is connected with each first oilhole
Logical oil circuit, the top of the insert body are equipped with the second oilhole being connected with oil circuit, the spool bottom be equipped with
The third oilhole that oil circuit is connected, the aperture of first oilhole are less than the aperture of third oilhole, the third oilhole
Aperture less than the second oilhole aperture, in coniform at first oilhole, the second oilhole, third oilhole and oil circuit connection,
The insert body bottom is equipped with the side oilhole communicated with oil circuit at third oilhole.
It being further improved as the utility model, the first oilhole quantity on the annular groove is 4, two neighboring the
Angle between one oilhole is 90 degree.
It is further improved as the utility model, the annular slot number is 2.
It is further improved as the utility model, the head of the insert body is additionally provided with the keyway for connection.
Compared with prior art, that the utility model has the advantage of structures is simple, manufacturing cost is low, and internal oil passages design is closed
Reason, oil liquid flowing is unobstructed, does not have clogging appearance.In simple terms, oil liquid enters in the oil circuit of insert body, spool sheet
Several the first oilholes communicated with oil circuit are provided in the annular groove of body, oil liquid can be flowed out from multiple first oilholes, can be effective
It avoids oil liquid to block in oil circuit, in addition, making at the first oilhole, the second oilhole, third oilhole and oil circuit connection in coniform
Oil flow is gentle, can effectively ensure that the stabilization of oil liquid flow.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model one；
Fig. 2 is the utility model structure diagram two.
Specific embodiment

As shown in Figure 1 to Figure 2: a kind of spool of economizer, including insert body 1, insert body 1 is cylindrical, spool
The side evagination of ontology 1 has several annulus 2, there are preset space length between two neighboring annulus 2, sets between two neighboring annulus 2
There is annular groove 3, annular groove 3 is equipped with several first oilholes 4, and several first oilholes 4 are spaced predetermined angular and circumferentially arrange, spool
The oil circuit being connected with each first oilhole 4 is equipped in ontology 1, the top of insert body 1 is equipped be connected with oil circuit second
Oilhole 5, spool bottom are equipped with the third oilhole 6 being connected with oil circuit, and the aperture of the first oilhole 4 is less than the aperture of third oilhole 6,
Aperture of the aperture of third oilhole 6 less than the second oilhole 5, the first oilhole 4, the second oilhole 5, at third oilhole 6 and oil circuit connection
In coniform, 1 bottom of insert body is equipped with the side oilhole communicated with oil circuit at third oilhole 6.
4 quantity of the first oilhole on annular groove 3 is 4, and the angle between two neighboring first oilhole 4 is 90 degree.
3 quantity of annular groove is 2.
The head of insert body 1 is additionally provided with the keyway 7 for connection.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
