Abstract
The invention discloses a diesel engine valve bridge. The diesel engine valve bridge is provided with a round hole, a groove and a contact face. The round hole and the groove can be connected in the axial direction in parallel in a sleeved mode. The contact face can be formed with a valve. According to the diesel engine valve bridge, normal movement of the valve can be ensured without a guide structure. The diesel engine valve bridge is simple in structure, small in weight, convenient to assemble, simple to manufacture and long in service life.
Description
Technical field
The present invention relates to diesel engine arts, particularly relate to diesel air valve bridge.
Background technology
Traditional four-valve diesel engine synchronizes to drive two axially in parallel air valve bridges to have guide frame, or and air valve bridge
The structure of contact is circular hole or waist type structure, and the design of this structure is to valve center and the phase of air valve bridge guiding centre
The highest to status requirement, typically up to less than required level, and center and the difference in height of air valve bridge
Make to produce lateral force between air valve bridge and guide frame thus inordinate wear occurs, thus cause damaging, reduce
In service life, it addition, traditional air valve structure is complicated, matching requirements are high, quality weight, and cost is high.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, it is provided that a kind of diesel air valve bridge.
The present invention is achieved by the following technical solutions:
The present invention provides a kind of diesel air valve bridge, described diesel air valve bridge be provided with can be socketed in axially in parallel
Circular hole and groove, and the contact surface that can be formed with valve.
Preferably, described diesel air valve bridge is provided with and the oilhole of described circular hole coaxial.
Preferably, described oilhole is through hole.
Preferably, described diesel air valve bridge is provided with dashpot.
Preferably, described dashpot is polygonal hole or circle.
Preferably, described polygonal hole is tetragon, hexagon.
Compared with prior art, the invention have the benefit that
(1) present invention need not guide frame, so that it may ensures valve proper motion.
(2) present configuration is simple, light weight, easy to assembly, is simple to manufacture, and service life is long.
Accompanying drawing explanation
