The valve horizontal type valve mechanism further comprises a camshaft, the axis of the camshaft is parallel to the plane where the valve push plate is located, and the wheel rims of at least one cam 1 and at least one cam 5 on the camshaft are abutted to the side plate faces, back to the throttle body, of the valve push plates 9 and 10. The 3/4 arc of the cam may be convex. The camshaft can be rotated by using a rotating shaft of an engine, so that the corresponding cam is driven to rotate and work, the cam serves as a driving part, the valve push plate serves as a driven part, and the valve push plate horizontally reciprocates under the driving of the cam.
In this embodiment, the air intake channel and the air exhaust channel are preferably arranged in the throttle body in a left-right manner, the air intake valve plate and the corresponding compression spring, the valve push plate and the cam belong to an air intake assembly, the air exhaust valve plate and the corresponding compression spring, the valve push plate and the cam belong to an air exhaust assembly, and the air intake assembly and the air exhaust assembly are arranged in a left-right manner.
The throttle body can be combined with the cylinder cover of the engine.
In order to ensure the smooth horizontal insertion of the air inlet valve plate and the air exhaust valve plate with the throttle body, the horizontal insertion positions of the air inlet valve plate and the air exhaust valve plate with the throttle body are respectively provided with a horizontally extending linear guide sliding fit structure, and the sliding fit positions preferably adopt a lubricating measure. The linear guide sliding fit structure can be specifically as follows: the throttle body is internally provided with a guide edge and/or a guide groove which extend linearly, the throttle body is correspondingly provided with the guide groove and/or the guide edge, and the guide edge and the guide groove which are respectively positioned on the two parts form linear guide sliding fit.
In the embodiment, the middle part of the throttle body is provided with a groove, the air inlet valve plate and the air outlet valve plate move along the groove, the lower surfaces of the air inlet valve plate and the air outlet valve plate are in contact with the groove of the throttle body, and the contact surfaces are lubricated.
The valve push plate can be provided with a flat-bottom groove with an indent on one side surface facing the throttle body, the compression spring abuts against one end of the valve push plate and abuts against the bottom of the flat-bottom groove, and the depth of the flat-bottom groove is preferably such that the compression spring can be completely positioned in the flat-bottom groove when being compressed to the maximum degree, so that the valve push plate can be completely attached to the corresponding end surface of the throttle body, and the complete plugging of a gap formed by the insertion connection between the air inlet valve plate or the exhaust valve plate and the throttle body is facilitated.
The position of the valve push plate completely abutted against the corresponding end face on the throttle body corresponds to the position of the valve push plate when the valve push plate reaches the highest point of the lift range, and at the moment, the air inlet valve plate and the exhaust valve plate are positioned at the positions for completely closing the air inlet channel and the exhaust channel.
The compression spring is always in a compression state in the whole return stroke range of the valve push plate, and when the valve push plate returns to a return stroke end point, the air inlet valve plate and the air outlet valve plate are in positions for completely opening the air inlet channel and the air outlet channel.
When the engine is in operation, the intake valve plate and the exhaust valve plate do not move in the vertical direction, but move in the horizontal direction. When the cylinder of the engine needs to intake air, the air intake valve plate does not seal the air intake channel; when the engine does not need to intake air, the cam props against the air intake valve plate to the inner end limit position to enable the air intake valve plate to close the air intake channel, and air cannot be intake; when the engine intake valve needs to be opened, the compression spring can pull back the valve push plate, so that the originally closed air inlet channel is opened. The mechanism can adjust the amount of intake air by adjusting the opening degree of the intake passage. The air inlet valve plate can not generate force action on the gas in the cylinder when being closed, so that the mixed gas in the cylinder can not be taken away, the air inflow of the engine can not be reduced, and the dynamic property is also ensured.
When the cylinder of the engine needs to exhaust, the valve push plate in the exhaust assembly is pulled back by the compression spring, the exhaust channel is opened, and the burnt waste gas is normally discharged. When the valve push plate is pulled back, the exhaust channel is fully opened, and the airflow is not influenced by resistance, so that the exhaust resistance is reduced.
The invention carries out innovative design on the throttle valve, changes the traditional up-and-down motion switching of the throttle valve into the existing left-and-right movement switching cover plate type throttle valve, and realizes the switching of the throttle valve by jointly controlling the left-and-right movement of the valve push plate by the rotation of the cam in cooperation with the compression spring.
