Variable blow hydraulic hammer
Because of variations in the ground and in the posts it is sometimes necessary to reduce the blow energy of the hammer. The present invention provides a device for use with a hydraulic hammer of the type that uses a back head gas chamber in which a gas pump and gas container is connected to the hammer back head gas chamber and the hydraulic energy of the hammer hydraulic circuit is used to pump gas from the back head chamber to said gas container to reduce the blow energy of the hammer. By reducing the pressure in the back head the blow energy can be incrementally reduced. In this invention the hydraulic circuit is tapped to provide energy to pump gas from the hammer gas chamber to a storage chamber to reduce the available hammer force. The transferred gas can be returned to the hammer gas chamber to restore the normal blow force.
