Abstract
The invention discloses a hydraulic tappet structure, which comprises a tappet body, wherein the tappet body is sequentially provided with a clamping ring and a clamping ring seat; the clamping ring is embedded into the clamping ring seat, and is connected with a plunger in which a flow limiting valve is arranged; the plunger is connected with a one-way valve; the one-way valve is connected with a one-way valve spring, and is arranged on a one-way valve seat; the two ends of the one-way valve spring are clamped between the one-way valve and the one-way valve seat. The hydraulic tappet structure is simple and high in valve sealing performance, abnormal noise of the hydraulic tappet is effectively controlled, and an engine can normally run.
Description
Technical field
The present invention relates to a kind of technical field of motor, be specifically related to a kind of hydraulic tappet.
Background technique
In the time that automobile moves in different environment, the wearing and tearing that motor bears are also different, and in motor car engine fault, hydraulic tappet structure is that rate of fault is higher, current hydraulic tappet is some problems of customer service preferably, but what on valve sealing and abnormal sound, all control is not fine.
Summary of the invention
Object of the present invention provides hydraulic tappet structure, solves one or more in above-mentioned prior art problem.
According to hydraulic tappet structure of the present invention, comprise cylinder, cylinder is provided with snap ring and retaining ring seat successively, snap ring is flush-mounted in retaining ring seat, and snap ring connects plunger, and plunger inside is provided with flow-limiting valve, plunger connects one-way valve, one-way valve connects check valve spring, and one-way valve is located at one-way valve seat, and check valve spring two ends inlay card is between one-way valve and one-way valve seat.
The hydraulic tappet structure that the present invention adopts, simple in structure, valve sealing is good, effectively controls the incorgruous of hydraulic tappet, makes engine operation normal.
Brief description of the drawings
Fig. 1 is the structural representation of the hydraulic tappet structure of one embodiment of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is described in more detail.
As shown in Figure 1, hydraulic tappet structure, comprise cylinder 1, cylinder 1 is provided with snap ring 2 and retaining ring seat 3 successively, snap ring 2 is flush-mounted in retaining ring seat 3, retaining ring seat 3 setting-ins or be set in cylinder 1, snap ring 2 connects plunger 4, plunger 4 one end are provided with flow-limiting valve 5, between plunger 4 and flow-limiting valve 5, form machine oil inner chamber, plunger 4 the other ends connect one-way valve 6, one-way valve 6 connects check valve spring 7, one-way valve 6 is sheathed on one-way valve seat 8, check valve spring 7 two ends inlay cards are between one-way valve 6 and one-way valve seat 8, between check valve spring 7 and one-way valve 6 and one-way valve seat 8, form good sealing.
The present invention is simple in structure, and good airproof performance is effectively controlled the abnormal sound of hydraulic tappet, and for ease of maintenaince.
The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
