Abstract : The patent relates to a fluid actuated piston having built in fluid flow control means in the form of a normally closed valve member of substantial mass. Inertia of the valve mass causes momentary opening of the valve during high accelerations of the piston and a spring closes the valve upon piston deceleration. The effect is to permit some loss of fluid through an exit passage during piston movement and hence to allow variation in the force applied to the piston by changes in spring rate, valve member mass and exit passage dimensions.
