Description
The utility model relates to a kind of motor, especially a kind of piston internal-combustion engine.
At present, the distribution device of traditional piston internal-combustion engine is by the crank-driven camshaft, drives by mechanisms such as rocking arms that reciprocating inlet and exhaust valve finishes again.Its structure is very complicated, and number of parts is a lot, not only manufacture cost height, poor reliability, and also the unbalanced motion noise of valve mechanism and impact noise are difficult to overcome.Because valve stem must pass from the intake and exhaust port of cylinder cap, air-flow will can enter cylinder after a lot of bother through valve guide bushing boss to valve port periphery in the cylinder cap air flue, has not only increased the air current flow resistance, but also has influenced the air inflow of motor.Therefore, the key factor that the principal element that existing valve mechanism form has become the restriction engine power performance to improve, the performance of valve mechanism have become the restriction engine reliability to improve.
The purpose of this utility model is to provide a kind of can reduce intake and exhaust resistance, increases the cylinder charge coefficient, improves power character and Economy, reduces noise, and simple in structure, the rotary valve formula explosive motor of reliable performance.
The utility model is realized by following technical proposal: it by the band piston cylinder and which is provided with the inlet and outlet road and place the cylinder cap on the cylinder to constitute, it is upper and lower two-layer to it is characterized in that cylinder cap is divided into, wherein lower floor's cylinder cap is provided with firing chamber, spark-plug hole or oil nozzle, the upper strata cylinder cap is provided with valve guide bushing, below valve guide bushing, be provided with the valve cage that is communicated with the inlet and outlet road, be provided with the valve formula valve of being with through hole and linking to each other with valve stem one end on it in the valve cage, the valve stem the other end is provided with the driver that actuating valve formula valve rotates.
Described valve formula valve is a valve retainer, through hole on it is at least one, the shape of through hole and size are with the inlet and outlet road and the firing chamber is suitable for reading adapts, rotation by valve retainer, make the through hole on it open and close the air-flow path that connects inlet and outlet road and firing chamber respectively, thereby finish air inlet, compression, acting, the exhaust work cyclic process of motor.Be provided with the anti-attrition sheet in the valve cage between described valve retainer top and the upper strata cylinder cap, the anti-attrition sheet is provided with the through hole that adapts with the inlet and outlet road junction, so that in guaranteeing normal inlet and outlet work, effectively reduce the wearing and tearing of valve retainer and can accurately control valve timing diagram.
Firing chamber end opening on the described lower floor cylinder cap links to each other with cylinder, inlet and outlet road on the cylinder cap of upper strata is communicated with the inlet and outlet menifold, fully open position at the inlet and outlet mouth, from motor inlet and outlet menifold, cylinder cap inlet and outlet road, anti-attrition film perforation, valve retainer hole to the firing chamber, constitute a uniform and smooth air-flow path, eliminate the throttling and the twists and turns of air-flow, reduced the flow resistance of intake and exhaust greatly.By changing the relative position of valve retainer center and cylinder axis, can realize that different cylinder cap air flues is arranged and the shape and the flow area size of change cylinder cap intake and exhaust port, also can change simultaneously the size of valve retainer and through hole thereof, help improving the volumetric efficiency of motor.
The described driver of being located on the valve stem is an actuation gear, by crank-driven, valve retainer is rotated by one group of driving mechanism, realizes the time opening at intake and exhaust road junction and closes.Be provided with antirattle spring between described actuation gear and the cylinder cap, be used to overcome the negative pressure that produces in the cylinder,, improve its service behaviour to keep valve retainer play downwards not in intake process.
The utility model compared with prior art has following advantage and effect: because such scheme, each cylinder of motor has been replaced the function of a plurality of to-and-fro motion valves by the valve retainer of a rotation, make the passage of intake and exhaust stream bigger, slicker and more sly, effectively reduce the resistance of inlet and outlet stream; The drive system of valve mechanism is simple and reliable, driving force reduces significantly, make motor have better power character, Economy, reliability, the unbalanced motion noise and the impact noise of valve mechanism have been eliminated, make motor have compact more, rational general structure simultaneously, reduced the manufacture cost of motor.Therefore, be a kind of more advanced, better piston internal-combustion engine.
