Abstract (en)
[origin: WO2006025146A1] 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.
