Abstract

510,864. Valve gear ; lubricating. TOWLER. C. Feb. 23, 1938, No. 14340/39. Divided out of 516,667, [Group XXIV]. [Classes 7 (ii) and 7 (vi)] A valve-actuating tappet comprises telescoping parts 1 and 6 enclosing a space 9 to which oil is supplied through ports 14, 16 which move out of coincidence when the tappet is in operation for opening and closing the valve, the two parts 1 and 6 being pressed apart also by a spring 13 which serves, in addition, to hold a valve 12 closed against an oil hole 11 leading to the socket 10 for the push rod. As the tappet reciprocates, the valve 12 becomes slightly unseated so as to allow a little oil to pass ; or a fine groove may be cut in the seating of the valve 12 for the passage of such oil. In a modification, the two parts of the tappet also have a buttress screwthreaded engagement with each other, which causes a slight relative rotation.
