Abstract: A needle selection module finger (30) is comprised of a finger member (31) and a finger holding member (40). The finger member (31) has a butt abutting portion (33) and a support (34). The support (34) has projections (35, 36) at its lower part. The finger holding member (40) has, from its one end toward the other end, a connecting portion (41) having concave parts (42, 42a) for accommodating the projections (35, 36) at the lower part of the support (34), a finger pivot support (43), and a piezoelectric body engaging portion (45). The finger member (31) and finger holding member (40) are positioned by inserting the projections (35, 36) of the finger member (31) in the concave parts (42, 42a) of the finger holding member (40), and are integrally connected to each other by inserting a pin 50 in holes (37, 37a) formed in the projection (35) and a connecting portion (41).

Abstract: A valve timing controller for varying the rotating phase of a cam shaft which drives a valve of an internal combustion engine. A pulley is disposed on the circumference of the cam shaft at an end to be freely rotatable. In the pulley, a first hydraulic chamber and a second hydraulic chamber are made, and these hydraulic chambers are separated in the circumferential direction of the pulley by a vane located on the circumference of the cam shaft. By controlling the pressures in the first and second hydraulic chambers, the vane is set selectively in a middle position, a valve timing retardation position which is an opposite position with respect to a pulley rotating direction and a valve timing advance position which is a farther forward position with respect to the pulley rotating direction. The cam shaft rotates with the movement of the vane.

Abstract: A variable lift height valve driving device which drives a valve of an internal combustion engine, varying the lift height of the valve. An inner shaft is disposed in a hollow cam shaft to be capable of reciprocating along the axis. A primary cam which has a primary cam surface is fitted around the hollow cam shaft at a specified position, and a secondary cam which has a secondary cam surface is fitted to the primary cam. With movement of the inner shaft, the secondary cam moves such that the secondary cam surface is set in a position to be on a level with the primary cam surface or in a position to protrude outward from the primary cam surface.
