Abstract (en)
[origin: WO2016074888A1] A hydraulic lash adjuster (20) adapted to be interposed in a hydraulic volume (V), between an actuator (18) and a control valve assembly (22) of a servo injector (10), said volume (V) being, in use, filled with fuel. The adjuster (20) comprises a lower piston (52) in which is slidably arranged an upper piston (46), an external spring (72) and an internal spring (64), both springs (72, 64) biasing the upper piston (46) toward the actuator (18). The lower piston (52) has a cylindrical cup-like shape with a peripheral wall (54) and a bottom wall (58) on which is arranged the internal spring (64) compressed between said bottom wall (58) of the lower piston (52) and the under- face of the upper piston (46).
