Abstract

See full text

A valve mechanism system in a hydraulic rocker arm for a combustion engine includes a check valve spring, a check valve ball and a control piston. The spring contacting the ball are arranged in a seat in a recess in the arm. The recess has a first opening to a rocker arm channel connected to a hydraulic element and a second opening to a rocker arm oil supply via a second channel. The piston has a first end with a pin axially aligned with the piston arranged in contact with the ball on the opposite side of the ball from the spring. The ball is movable between a first position allowing oil to flow to and from the oil supply and a second position stopping oil from flowing between the two channels. A control piston spring is arranged on a second end of the piston such that it biases the piston towards the ball. The piston in an axial direction is movably arranged in a cylinder shaped cartridge and the cartridge has a first end arranged towards the outside of the arm and a second end in the axial direction opposite inner end. The cartridge is arranged in the recess in the arm.
