The influence of the poppet angle and the oil temperature on the flow characteristics and the cavitation phenomena of an oil hydraulic poppet valve are studied experimentally using a half cut model. The following results are obtained. A change of the poppet angle has great effect on the pressure distribution and the flow contraction degree in the restriction between the poppet surface and the valve seat. Hence a remarkable effect of it appears on the valve performances especially when the chamfer is on the seat. The effect of the oil temperature is explained generally by a change in viscosity and Reynolds number.
