Title: Variable Frequency Hydraulically Reciprocated Impact Tool
IPC: F01L23/00
Filed: 1979-03-16
Abstract: A pressurized fluid oscillator which may be used in an impact tool to provide blow frequency and energy control. The oscillator has a valve 14 and hammer 12 which are movably disposed in a cavity in which pressurized fluid is switched between supply and return alternately by the valve as it travels in the forward and return direction so as to effect oscillation of the hammer. A pocket 102 extends into the cavity into which the valve enters during forward movement after it has been engaged by the hammer and has switched pressure in the cavity. The hammer is provided with a passage 116 which provides communication of the fluid trapped in the pocket through a channel 104, 105 to supply. Control of fluid flow through the channel during predetermined intervals of time is effected by valve 106, to control both the frequency and length of hammer stroke and thus the blow frequency and blow energy of the oscillator. <IMAGE>
