WIPO Patent Application WO/2018/233386
Kind Code:
A1
Abstract:
An exhaust valve (100), comprising a valve (1) that can rotate around a pivot (11), and a hydraulic mechanism (2). The hydraulic mechanism comprises a hydraulic cylinder (21), a piston (22) in the hydraulic cylinder, a return spring (23) that presses against the piston, and a connecting rod (24) connected to the piston; the connecting rod is connected to the valve; rotation of the valve can simultaneously drive the connecting rod and the piston to move in the hydraulic cylinder. According to the exhaust valve, a damping effect is achieved by means of the hydraulic mechanism; thus, the speed at which the valve rotates is low, the valve is prevented from quickly touching a base, and the touch force and noise are reduced.
