Abstract: A strut includes a first end, a second end, a cylinder and a piston, wherein the piston is mechanically coupled to the first end and the cylinder is mechanically coupled to the second end. A fluidic chamber is formed between the cylinder and the piston. A first fluidic passageway fluidly couples the fluidic chamber and a fluidic reservoir, and a second fluidic passageway fluidly couples between the fluidic chamber and the fluidic reservoir. A check valve includes an open-biased moveable valve element coupled to a balance spring, and the valve element interacts with a valve seat to control fluidic flow through the second fluidic passageway. The valve element is responsive to urging of the balance spring.

Abstract: A dynamic harmonic balancer for mounting on a crankshaft of an internal combustion engine includes an element defining a cavity. The dynamic harmonic balancer also includes a body of fluid disposed within the cavity. The dynamic harmonic balancer additionally includes a plurality of pellets disposed within the body of fluid and configured to shift within the cavity. The shifting of the pellets within the cavity counteracts an imbalance in the harmonic balancer and damps crankshaft torsional vibrations during operation of the engine. An engine having such a dynamic harmonic balancer is also disclosed.

Abstract: A screw assembly for operatively connecting a first component to a second component is provided such that the first and the second components are separated by a clearance when operatively connected by the assembly. The assembly includes a screw member defining a screw opening and a linking member defining a link opening. A fastener is configured to transfer a driving torque to the linking member when the fastener is rotatably driven into the link opening. A threaded portion of the fastener is configured to engage with the link opening. The linking member is configured to transfer the driving torque to the screw member, thereby moving the screw member until a second screw end of the screw member contacts a mounting face of the second component. The fastener may be configured to pass through the linking member and enter a second cavity in the second component.
