Title: Device for use in operating a valve
Inventor: BONELLO LUIS NICOLAS
IPC: F16H53/06
Filed: 1969-09-25
Abstract: 1,221,606. Cams. L. N. BONELLO. 25 Sept., 1969 [25 Sept., 1968], No. 47365/69. Heading F2K. A valve tappet for an I.C. engine has a twoarmed lever 8 pivoted thereto, one arm engaging a plunger 10 slidable within the tappet 1 and the other arm being engaged by a fixed abutment 5 when the tappet moves, the resultant pivotal movement of the lever 8 causing displacement of the plunger 10 in the tappet. The total travel of the plunger is thus greater than that of the tappet. The end of a key 5 between the tapped and a guideway 7 forms the abutment. A push-rod 11 engages the plunger 10.
