Abstract

The invention relates to a novel engine valve tappet which comprises a tappet base, an inner tappet chamber, an oil return tube outlet groove and an oil return tube, wherein the valve tappet is in a straight cylinder shape; the oil return tube outlet groove is arranged on the outer surface of the end part of the tappet base; an inlet end of the oil return tube is arranged on an inner wall of the inner tappet chamber; an outlet end of the oil return tube is arranged on the oil return tube outlet groove; the end face of the tappet base is arranged as a spherical surface. The novel engine valve tappet has a simple structure. The end face of the tappet base is arranged as the spherical surface, so that the strength of the end face of the tappet base is increased, the blocking and breaking probability of the tappet is reduced and the normal working of the engine is ensured.

Description

New work engine valve tappet
Technical field
The present invention relates to new work engine valve tappet, belong to technical field of engines.
Background technique
Valve tappet is a critical piece in valve transmission group, and tappet is the driven member of cam, and its effect is that the motion from cam and active force are passed to push rod or valve, also bears the lateral force that cam applies simultaneously and is passed to body or cylinder head.
Tappet is in when work, and its bottom surface contacts with cam, and because area of contact is little, contact is large, therefore weares and teares relatively serious, of long duration stuck phenomenon of rupture can occur, thereby has affected engine work.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of simple in structure, tappet body base end face intensity is high, reduces the Novel valve tappet of the stuck fracture probability of tappet.
The technical solution adopted in the present invention is for this reason: comprise that tappet body base, tappet inner chamber, return tube go out port recess and return tube, described valve tappet is straight tube shape, described tappet body base end outer surface is provided with return tube and goes out port recess, the entrance point of described return tube is located on the inwall of tappet inner chamber, the outlet end of return tube is located at return tube and goes out in port recess, and the end face of described tappet body base is sphere.
The spherical radius of described tappet body base is SR1500mm~SR49000mm.
Advantage of the present invention is: the present invention is simple in structure, by tappet body base end face is made as to sphere, thereby has improved tappet body base end face intensity, has reduced the probability of the stuck fracture of tappet, has ensured engine work.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure, 1 is tappet body base, the 2nd, tappet inner chamber, the 3rd, and return tube goes out port recess, the 4th, return tube, the 5th, sphere.
Embodiment
New work engine valve tappet, comprise that tappet body base 1, tappet inner chamber 2, return tube go out port recess 3 and return tube 4, described valve tappet is straight tube shape, described tappet body base 1 end outer surface is provided with return tube and goes out port recess 3, the entrance point of described return tube 4 is located on the inwall of tappet inner chamber 2, the outlet end of return tube 4 is located at return tube and goes out in port recess 3, and the end face of described tappet body base 1 is sphere 5; Sphere 5 radiuses of described tappet body base 1 are SR1500mm~SR49000mm.
