PURPOSE: A hydraulic control proportional relief valve is provided to keep the speed and displacement uniform using a symmetric cam and a gear to convert the rotary motion of a step motor into the linear motion. CONSTITUTION: A hydraulic control proportional relief valve comprises a connect plate, a housing, and a controller(10). The connect plate connects a driving part(20) at one side. The housing is placed and connected at the other side of the connect plate. The controller is equipped inside the housing. The controller accurately uniformly maintains the speed and displacement at desiring step according to the step angle, while converting the rotary motion of a step motor into the linear motion. |
