Abstract

A hydraulic valve lift system and an engine therewith, and a method of its operation, the hydraulic valve lift system comprising a lift piston (12) sliding reciprocatingly inside a pump cylinder (11) to pump a portion of a hydraulic fluid to a valve system, where the size of the part can be regulated by turning the pump cylinder (11) in relation to the lifting piston (12).
