Abstract
An anti-lash adjuster for compression relief brakes on internal-combustion engines. The anti-lash adjuster has a slave piston adapted to contact the valve-actuating mechanism for the exhaust valves. The slave piston has a predetermined surface area and a retracting spring which biases the slave piston to a retracted position. A forward bias unit is provided to assist oil under engine-oil pressure in overcoming the retracting force to bias the slave piston to an extended position. The forward bias unit only assists the engine-oil pressure in overcoming the retracting force over a limited distance. The distance may be selected to keep the exhaust valves open throughout brake operations or only to take up the lash during brake operation or to take up part of the lash. A master piston is provided to further open the valves during portions of brake operation. There is means, such as an aperture extending through the slave piston, to prevent the slave piston from moving away from the forward bias unit. The forward bias unit normally seals the aperture when in contact with the slave piston.
