RC Digger

The hydraulic lever of the RC digger realizes the hydraulic control of the excavator’s arm through the mini hydraulic pump. Or add a remote control module. Just use several remote control modules for several actions.

Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into the pressure energy of liquids. The cam is driven to rotate by a motor. When the cam pushes the plunger upwards, the seal volume formed by the plunger and the cylinder body is reduced, and the oil is squeezed out of the seal volume and discharged to the place where it is needed through the one-way valve. When the cam rotates to the lower part of the curve, the spring forces the plunger down to form a certain degree of vacuum, and the oil in the oil tank enters the sealed volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously, the sealing volume periodically decreases and increases, and the pump continues to work.
