Abstract
A vibrating device comprising in combination a cylinder with a piston, having a piston rod, pore means to cause a reciprocating movement in said piston inside said cylinder, a source of hydraulic pressure, a valve case with a valve body to provide hydraulic fluid from said pressure source to said cylinder in order to subject the piston side of the piston rod to a permanent pressure of said pressure source, means to alternately connect the opposite side of said piston with the pressure source and with a outlet for said fluid, respectively, according to the position of the valve body, and means for urging said valve body by the movement of said piston by means of at least one spring means acting on the piston during all its movement.
