AUXILIARY VALVE DRIVING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2024/051732
Kind Code:
A1
Abstract:
An auxiliary valve driving mechanism (100), comprising a box body (210), connecting rods, a starting piston (162), and a driving piston (130). The starting piston (162) is provided in a starting piston hole (260) of the box body (210); the driving piston (130) is provided in a driving piston hole (190); the connecting rods comprise a first connecting rod (184) and a second connecting rod (186); the end face of a first end of the first connecting rod (184) is connected to the box body (210) by means of a rotating pair (122); the end face of a second end of the first connecting rod (184) is connected to the end face of a first end of the second connecting rod (186) by means of a rotating pair (125); a rotating pair (128) is provided between the end face of a second end of the second connecting rod (186) and a first end face of the driving piston (130); and a second end face (131) of the driving piston (130) is located above a valve of an engine. A guide groove (137) is formed at an end (134) of the starting piston (162); the second end of the first connecting rod (184) and the first end of the second connecting rod (186) are located in the guide groove (137); and the first connecting rod (184) and the second connecting rod (186) do planar motion between a "closed" position and an "open" position along the guide groove (137), so that the driving piston (130) moves up and down. A non-operation position and an operation position of the auxiliary valve driving mechanism (100) are obtained, and auxiliary valve motion for the engine is generated, comprising valve motion for engine braking.
