Description
Technical field
The utility model relates to piston internal-combustion engine, more particularly, relates to the distribution device of piston internal-combustion engine.
Background technique
The four-stroke piston explosive motor all has a cover distribution device, and existing distribution device is complex structure, rate of fault height not only, and it is big to take up room, and the noise during work is also very big.In order to solve existing air distribution structure complexity, problem that rate of fault is high, people have carried out a large amount of research to traditional valve and valve driving component.Because traditional distribution device uses parts such as cam, valve, valve seat, valve guide bushing, noise is big when not only working, and working life is short.Distribution device working life should be consistent with the motor bulk life time, but existing distribution device working life well below the motor bulk life time, especially parts such as cam, valve, valve seat, valve guide bushing are easy to wearing and tearing or lost efficacy in to-and-fro motion.In order to solve the problem that prior art exists, the gap of people in eliminating distribution device reduces aspects such as the impulsive load of part and noise and carried out very big effort, also must compare Design of Cam Profiles suddenly simultaneously, makes valve opening and closes the faster measure of Denging.But these measures also fundamentally do not solve the problem that distribution device exists.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of I. C engine distribution mechanism that uses rotary valve plate, and it realizes control to the inlet and outlet door by rotary valve plate, and is not only simple in structure, and reliable in action.
The purpose of this utility model is achieved in that a kind of I. C engine distribution mechanism that uses rotary valve plate, comprise enclosing cover, inner cap and rotary valve plate, enclosing cover is associated with the mechanism that is connected cylinder block with the inner cap knot, enclosing cover and in cover suction port and relief opening all arranged, the suction port that covers outward, relief opening with in the suction port, the relief opening that cover overlap; Rotary valve plate has valve opening, rotary valve bobbin and transmission position on the rotary valve plate between enclosing cover and inner cap, rotary valve plate and enclosing cover and inner cap constitute can relatively rotate structure; The suction port and the relief opening of inner cap are provided with seal ring.
On the such scheme basis, the utility model also has following further step:
The suction port of described inner cap and relief opening have depression position or groove, and seal ring places depression position or groove.
Transmission position on the rotary valve plate is gear or sprocket wheel, or synchronous pulley.
Described seal ring has elastic component.
Described seal ring is a ceramic-seal ring.
The valve opening of described rotary valve plate and inner cap, the suction port that covers outward, relief opening are the class fan shaped borehole.
Advantage of the present utility model is as follows:
Because, enclosing cover and in cover suction port and relief opening all arranged, the suction port that covers outward, relief opening with in the suction port, the relief opening that cover overlap; Rotary valve plate has valve opening, rotary valve bobbin and transmission position on the rotary valve plate between enclosing cover and inner cap, rotary valve plate and enclosing cover and inner cap constitute can relatively rotate structure; The suction port and the relief opening of inner cap are provided with seal ring.So when inside and outside lid assembly parts connects cylinder body, and the transmission position of rotary valve plate can replace traditional distribution device when rotating by driving component binding engine bent axle.Rotary valve plate is in rotary course, when the valve opening on the rotary valve plate can communicate with the inside and outside row who covers, suction port are identical respectively successively, finished no reciprocating rotation distribution action, thereby thoroughly eliminated wearing and tearing and noise that numerous parts such as cam, valve, valve seat, valve guide bushing produce in to-and-fro motion.The utility model is not only simple in structure, and reliable in action, and consumed power is few, and rate of fault is low, and the life-span is long, and frequent adjusting play in the use especially is fit to four-stroke compression ignition engine and four-stroke spark ignition motor.
