Claims

[Scope of utility model registration request]

A multi-valve engine consisting of a crosshead slidably supported by a crosshead pin of an intake/exhaust valve of a multi-valve engine, a valve stem that engages head pieces at both ends of the crosshead to move up and down, and a rocker arm that engages the upper surface of the crosshead. In the valve engine, oil is supplied from the oil supply passage between an oil supply passage that extends through the rocker arm and opens near the center of the crosshead, and the crosshead pin that is provided near the center of the crosshead. and an oil supply passage provided in the crosshead, extending from the space between the crosshead and the crosshead pin to the head piece, and opening at the engagement surface with the valve stem. Valve lubrication system for multi-valve engines.
