Problems solved by technology

Internal combustion engines having poppet valve systems actuated by push rods that operate generally at high engine speed, or having aggressive valve actuation, commonly experience levels of induced vibration and dynamic motions in the valve system.
Such vibrations adversely affect the valve system and engine performance.

Embodiment Construction

[0014] In one specific embodiment of the present invention there is provided an improved push rod for actuation of rocker arms and poppet valve actuation for internal combustion engines. The improved system embodies a push rod having a vibration dampening elastomeric component bonded along the longitudinal length to the diameter of a tubular push rod.

[0015] In another specific embodiment of the present invention there is provided a push rod having a vibration dampening elastomeric component bonded along the longitudinal length having an added tubular outer component cover bonded to the elastomeric. The outer cover generally being thin metal tubing. The outer covering component is not limited to metal tubing; in certain applications materials such as high strength tape may be tensioned wrapped to provide resistive reaction to vibration force transmission. Embodiment of the cover provides a further means of absorbing vibration energy and amplitude.

Abstract

The present invention provides an improved push rod for actuating poppet valves in internal combustion engines. The improved push rod provides a vibration dampening beam member to alter push rod vibration frequency spectrum, levels and amplitude introduced through push rods to valve systems. Reducing push rod vibrations and amplitude improve valve system and engine performance.

Description

CROSS-REFERANCE TO RELATED PATENT APPLICATION [0001] This is a non-provisional application relating to and claiming the benefit of U.S. Provisional Patent Application Ser. No. 60 / 755,455, Filed Jan. 3, 2006.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to the field of internal combustion engines pertaining to poppet valve operating systems having rocker arms actuated by push rod and cam, particularly a push rod beam member providing means to dampen vibration by an elastomeric component and outer cover embodiments. [0004] 2. Description of Background Information [0005] Internal combustion engines having poppet valve systems actuated by push rods that operate generally at high engine speed, or having aggressive valve actuation, commonly experience levels of induced vibration and dynamic motions in the valve system. Such vibrations adversely affect the valve system and engine performance. The primary dynamic responding members of the ...
