摘要： A method of fabricating a piston for use in an automobile by welding. The head section and the skirt section of the piston are separately fabricated by casting such that these sections form the top wall portion of the piston when joined together and that the abutting surfaces of these sections form a portion of an oil circulating passage. Then, these sections are connected and welded together using an electron beam.

摘要： 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.
