Abstract: An adjustable-stroke solenoid valve assembly includes supply, control, and exhaust ports, an inner cavity having first and second seats, a solenoid coil, and a plunger assembly. The plunger assembly includes an armature shifted by the coil. The plunger assembly also includes a stem having a first end adjustably engaged with the armature, and a second end adjustably engaged with a poppet. The plunger assembly additionally includes a first surface that gets pressed against the first seat to block fluid flow to the control port when the coil is de-energized and a second surface that gets pressed against the second seat to facilitate fluid flow to the control port when the coil is energized. Adjustment of the stem's first end relative to the armature and of the poppet on the stem's second end establish a predetermined stroke for the plunger assembly and a predetermined fluid flow rate to the control port.

Abstract: A variable valve actuation apparatus for an internal combustion engine includes a first link arm which has a projected portion that is engageable with and disengageable from a guide rail, and which is displaceable in the axis direction of a camshaft, and a link shaft linked to the first link arm in such a manner as to allow rotation but constrain movement in the axis direction. When an electro-magnetic solenoid is electrified, the first link arm rotates about the link shaft so that the projected portion engages with the guide rail. In association with the displacement of the link arms that occurs during the engagement, the state of motion of second rocker arms changes, so that the opening characteristic of valves provided for each cylinder is switched.
