Title: Tappet
Inventor: KURAMOCHI EIJIRO
IPC: F01L1/16
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent the separation of a sliding plate and to improve the durability in a tappet for engine in which the ceramic sliding plate is attached to a face to be kept into contact with a cam of the tappet, by cutting a peripheral edge of a composition plane of the sliding plate, to form a diameter smaller than an outer diameter of the sliding face. SOLUTION: In a tappet 1 used in a valve system or the like for an engine, a peripheral edge part 4b of a composition plane 4 of a tappet body 2 and a ceramic sliding plate 3, is cut, to form a diameter smaller than an outer diameter of the sliding face 3a of the sliding plate 3. That is, the composition plane 4 comprises the diameter reduced by cutting the edge parts opposite to each other, of the tappet body 2 and the sliding plate 3, and a sectional form of a part obtained by cutting the peripheral edge part 4b of the composition plane 4, is an U-shaped circular groove 9, which disperses the sudden change of the stress (stress concentration). Whereby the static residual stress acting in a direction for separating the sliding plate 3 from the tappet body 2, generated on the peripheral edge part 4b of the composition plane 4, can be reduced, and the separation of the sliding plate 3 can be prevented.

Abstract: PURPOSE:To obtain optional FS (frequency shift) modulated waves in the same modulation speed by applying outputs of a DELTAF (frequency shifting width of FS modulated wave) setting circuit and an FL (low frequency of FS modulated wave) setting circuit to an adder and then to a divider circuit. CONSTITUTION:The standard frequency of a quartz oscillator 1 is applied to a variable dividing circuit 2. An divided output of the circuit 2 is outputted from a terminal 8 through an LPF 3. An FS modulated signal is inputted from a terminal 7 to an adder 10, a set point DELTAM of a DELTAF setting circuit 9 is inputted to terminals S1-Sn and a set point ML of an FL setting circuit 5 is inputted to terminals R1-Rn.
