Abstract: A hydrofoil (1) comprises a bottom (23) formed with two front and rear steps (3 and 4), and a strut (31) supporting a submerged hydrofoil (21) arranged between the two steps (3 and 4). The strut (31) can be switched between a storage state and a navigation state by its forward-and-backward rotation. A threshold value of dynamic lift (F) obtained by the hydrofoil (21) can be established arbitrarily, and the dynamic lift can be held to the set value by keeping the strut (31) in the navigation state correspondingly to the established threshold value of hydrofoil-dynamic-lift, thereby enabling the dynamic lift to be held at the established value during navigation. Moreover, based on draft (WL) or trim angle (TR) during the boat-berthing, a set value of hydrofoil-dynamic-lift and a set value of tilt angle of a propulsor (22) or a flap (22a) attached to the rear of hull can be accommodated.

The feedback mechanism ensures that the stroke of the hydraulic actuator is proportional to the magnitude of the electric current applied to the operator regardless of variation of the fluid pressure applied to the driver piston.

Abstract: An engine valve train has oil flow to valve actuating components cut off or restricted when the valves are closed, to reduce parasitic losses. In an exemplary embodiment, a pushrod has a pivotable connection with a valve actuating rocker arm through which internal oil passages conduct oil for lubricating the rocker arm.

Misalignment of the passages at the sliding connection reduces the amount of oil flow through the connection to improve engine efficiency. When applied to cylinder deactivation engines, oil flow to rocker arms of deactivated valves is completely cut off, or reduced, further reducing parasitic losses.

Abstract: An internal combustion engine having a centrifugally-responsive vacuum release mechanism that relieves a vacuum within a combustion chamber during the expansion stroke of an engine at engine starting speeds. The vacuum release mechanism is disposed adjacent the cam and engages a cam follower at engine starting speeds to unseat an engine valve while an engine piston is moving toward a crankcase and away from the combustion chamber. When the engine rotation speed reaches a desired kick-out speed, the centrifugal force transitions the vacuum release mechanism from an engaged position to a disengaged position. The vacuum release mechanism engages the cam follower to separate the cam follower from the cam when the vacuum release mechanism is in the engaged position. When the vacuum release mechanism is in the disengaged position during normal operating speeds, the cam follower is permitted to contact the cam throughout the entire rotation of the cam.
