Abstract

The invention provides an intake valve connecting device with turbulence, deformation prevention and no valve clearance; and the intake valve connecting device mainly comprises a valve head, a valve rod, a spring base, a spring, an elastic cushion and a valve cover. The intake valve connecting device is characterized in that the valve head has a turbulence effect; the valve rod is high in strength, and prevents the deformation; and no valve clearance is formed between a valve and a rocker arm. As the section on the valve head is a parallelogram, and is provided with a convex ring inwards inclined, the valve head has functions of increasing the intake quantity, guiding fluids and generating vortexes; transverse invar steel rods and longitudinal invar steel rods are vertically staggered on the valve rod for reinforcing the strength of the valve rod and inhibiting the expansion of the valve rod; the elastic cushion with a high-elasticity rubber material realizes zero clearance of the valve; the valve sleeve with an aluminum alloy material realizes quick heat dissipation of the valve rod; and invar steel clamping rings restrain the expansion deformation of the valve sleeve.

Description

technical field [0001] The invention relates to a flow-disturbing, deformation-resistant intake valve connection device without valve clearance, in particular to a protruding ring with a parallelogram-shaped cross-section on the valve head and an inward inclination, so that it can increase the intake air volume, The function of guiding the fluid and generating the vortex; the strength of the valve stem is strengthened and the expansion is restrained through the vertically staggered horizontal constant range steel rods and longitudinal constant range steel rods on the valve stem; the valve is realized through the elastic pad of high elastic rubber material. The zero clearance of the valve cover; the rapid heat dissipation of the valve stem is realized by the valve cover of aluminum alloy material; the expansion and deformation of the valve cover is suppressed by the constant range steel snap ring, which belongs to the technical research and development field of engine valves. ...
