Abstract
A hydraulic ram comprises a cylinder having a piston carrying a rod member extending through an end wall of the cylinder and adapted to be connected to a hammer weight, said cylinder having means for achieving flow of fluid to and from the head space between the piston and said first end of the cylinder, and a valve mechanism located at or adjacent the other end of the cylinder characterised in that: a) the valve mechanism comprises a valve sleeve member journalled within the cylinder and having with the cooperating wall of the cylinder a circumferential gallery adapted to be in communication with fluid at elevated pressure at all positions of the sleeve; b) the cooperating cylinder wall has one or more ports adapted to place gallery in communication with either the said head space or a port for discharging fluid from the cylinder; c) a sleeve position control chamber encompasses one end of said sleeve and is adapted to be put in communication with either a low or a high pressure zone; and d) the relative radial components of end faces of the portion of said gallery carried by said sleeve and the end face of said sleeve exposed to the fluid in said control chamber are such that the sleeve is either in a biassed position with said head space in communication with the discharge port or it is in an unbiassed position with said head space in communication with said gallery.
