Problems solved by technology

This leads to a small section in the guide hole of the valve bridge that cannot be used for guidance, which is a waste of vertical space, resulting in a low space utilization rate of the guide hole of the valve bridge

Abstract

The invention discloses an air valve bridge with increased pilot fit length. The air valve bridge comprises an air valve bridge guide rod and an air valve bridge body, wherein the air valve bridge body is provided with an air valve bridge guide hole; the air valve bridge guide hole is used for mounting the air valve bridge guide rod. The air valve bridge is characterized in that the bottom of theair valve bridge guide hole is provided with an air valve bridge inner expansion hole; the diameter of the air valve bridge inner expansion hole is larger than that of the air valve bridge guide hole,so that the air valve bridge guide rod can extend into the air valve bridge inner expansion hole. By adopting the air valve bridge, the bottom of the air valve bridge guide hole is provided with theair valve bridge inner expansion hole, so that the pilot fit length is improved, and the space is used fully. Moreover, an oil storage space is added, so that lubrication is facilitated.

Description

technical field [0001] The invention relates to the technical field of engine devices, in particular to a valve bridge with increased guiding and fitting length. Background technique [0002] As we all know, the valve bridge is mainly the mechanism used by the rocker arm to push the valve. There are two types of valve bridges in terms of structure, namely valve bridges with guiding structures and valve bridges without guiding structures. Wherein, the valve bridge with the guide structure includes a valve bridge guide hole and a valve bridge guide rod, wherein the valve bridge guide hole is used for installing the valve bridge guide rod. Through the valve bridge guide rod fixed on the cylinder head, the valve bridge can only move up and down without lateral sliding, preventing the valve from being eccentrically worn due to lateral force. [0003] Such as the valve bridge structure disclosed in patent CN203532082U, but due to the influence of the layout space, the matching l...
