HYDRAULIC HOUSING OF AN ELECTROHYDRAULIC VALVE ACTUATING MECHANISM

摘要

A hydraulic unit for an internal combustion engine is proposed - having an electrohydraulic valve actuating mechanism, comprising - a hydraulic housing (2) with a receiving opening (33), - a piston guide (32) which is caulked with the receiving opening, and a pump piston (8) which is guided longitudinally movably therein, - and a cam follower which is configured as a tappet for transmitting a cam elevation to the pump piston. The tappet is to be configured as a bucket tappet (23, 23') with a cam tapping surface and a bucket skirt (24) which is guided longitudinally movably in a tappet guide (25) of the hydraulic housing.
