Linear actuator apparatus and actuating control method

When an inlet valve is opened or closed via a first mover, by the operation of a first linear actuator, energy accumulated by a first spring or a second spring is discharged by the operation of a second linear actuator, to transmit the energy to the inlet valve via a second mover and the first mover. As a result, the inlet valve can be opened or closed at a high speed, with higher energy efficiency and has an improved durability.

Electromagnetically driven valve

An electromagnetically driven valve (10) includes a driven valve (14) having a stem (12) extending in a prescribed direction and an umbrella-shaped portion (13) provided at a tip end of the stem (12) and opening/closing an intake/exhaust port, a lower disc (20) and an upper disc (30) having one ends (22, 32) coupled to the stem (12) and the other ends (23, 33) supported by a disc support base (51) so as to allow free oscillation of the disc respectively and oscillating around the other ends (23, 33) so as to cause the driven valve (14) to carry out reciprocating motion in the prescribed direction, a lash adjuster (16) provided in the stem (12), and a guide ring (45) guiding the lash adjuster (16) along the prescribed direction. The lash adjuster (16) contracts and expands in the prescribed direction and accommodates displacement of the stem (12) produced in a direction orthogonal to the prescribed direction as a result of reciprocating motion of the driven valve (14). With such a structure, the driven valve carries out smooth reciprocating motion.
