1. The construction of a new type anti-pitting tappet with a cast hole in its end face and isothermally treated are described.

2. The factory is Tappet car engine and hydraulic piston pin the specialized production enterprises.

3. Cam shaft and tappet body are important parts of engine, their status will influence directly whether or not the engine could make normal operation.

4. Lift the ram and position the tappet ( with the ball bearing ) inside the tester cup.

5. Based on the geometrical relation between tappets and cams, uniform formulas for mutual lift-range transition between flat based tappet, roller(or sphere)tappet and cone tappet were presented.

6. Phosphating is usually applied to the cam and tappet of engine for the inhibition of early scratch.

7. Composite structure tappet composed of steel body and ceramic disk has a better wear resistant and wear properties , and service ability than the using alloy tappet.

8. A sort of hydraulic tappet is designed for a certain small-capacity high-speed engine.

9. The utility model aims at providing a combined hard alloy tappet which has a high fatigue resistance and a large allowable contact stress.

10. Description : Zhejiang Pingchai Pumps ---- Oil pump , tappet valve guide, rod.

11. Of course,() the fundamental solution to the problem or to improve the tappet of the material and size accuracy.

12. In order to deeply comprehend the wear regularity of chilled alloy cast iron tappet, the influence of surface layer microstructure on wear resistance was studied.

13. Valve-face wear. In addition to the conditions discussed above, excessive tappet clearance or dirt on the valve face or seat could cause Valve-face wear.

14. The key problem of structural design of ceramic-metal composite tappet rod is the connecting manner.

15. Our company mainly product oil pump, valve guide, valve Tappet, push rod and so on.

16. The paper analyzes in details the wear reasons of engine tappet rod and proposes the relative measures for improvement based on the statistical data on metal troubles from our department.

17. The reason of the formation of gas porosities and cracks on the head face of valve tappet has been studied.

18. Valve Breakage. Any condition that causes the valve to overheat or to be subjected to heavy pounding (as from excessive tappet clearance or from detonation ) may cause valves to Break.

19. The model and linear study on the exhaust cam of internal-combustion engine is of great importance to knowing about the linear features of cam's shell and the law of tappet movement.
