Abstract
A variable cylinder device for internal combustion engines having a movable rocker arm and a movable rocker shaft in which an oil-supplying type lash adjuster is fitted to a housing having a main oil-passage and the rocker shaft is secured to a rocker support. Oil for lubricating the sliding surface of movable rocker shaft is supplied from the main oil-passage through a series of passages formed in the housing and the rocker support, especially through a pipe protruding from the rocker support and slidably inserted into the housing. The housing is further provided with a mechanism for reducing the oil-pressure in the main oil-passage and a mechanism for preventing rotation of the rocker support.
