Title: Valve of speed increase for crusher
Inventor: KANG DEUK SU
IPC: B66C13/00
Filed: 1998-11-25
Abstract: PURPOSE: A speed increase valve for a crusher is provided to prevent the operation of a cylinder rod even if oil leakage or the formation of pressure is occurred in a main control valve of an excavator. CONSTITUTION: Two channels are formed to be communicated to a second cylinder port(CP2) in a spool(16). Two channels(30,32) are formed in the spool additionally. By making two closed spaces formed by a sleeve(14) and the spool, the channel of hydraulic oil is maintained in closed mode in the initial node of a speed increase valve. When a main control valve is maintained in neutral state, the pressure or oil leakage occurring in the main control valve is blocked up. By providing a two-stage spring to a spring seat(24), the speed increase valve converts the initial mode to a speed increase mode in low pressure by an inner spring(26). But the conversion from the speed increase mode to a normal mode is performed in high pressure by an outer spring(28). The pressure loss and resistance occurring when the hydraulic oil passes the speed increase valve is minimized by the slope angular degrees formed on the ends of the channels in the spool.
