摘要： A fluid powered rotary actuator having a first member which is pivotally connected to a second member and which is includes at least one toroidal shaped spear or piston which acts within a correspondingly shaped toroidal shaped cylinder to move the first member relative to the second member. The or each toroidal shaped spear or piston and cylinder assembly includes seals mounted within a seal carrier and the configuration allows movement of the seals relative to the or each cylinder. This configuration allows the seals to continue to provide a leak resistant hydraulic seal between each toroidal shaped spear or piston and its associated cylinder even in cases where the toroidal shaped spears or pistons deflect relative to their associated cylinders. The cylinders are also mounted to the first or second members in a manner designed to reduce the chance of tensile cracking due to deflection of the cylinders.

摘要： A powertrain has a continuously variable transmission including a shaft rotatable about an axis. The CVT further comprises a variator assembly that includes a pulley supported on the shaft. The pulley has a movable sheave with a ramp surface. The movable sheave is axially movable on the shaft. The variator assembly also includes an endless rotatable device frictionally engaged with the movable sheave. An actuator mechanism includes a wedge component supported on the shaft. The wedge component has a wedge surface that automatically engages the ramp surface when torque on the shaft is in a first direction. The wedge surface applies a wedge force on the ramp surface. The actuator mechanism further includes an actuator that is operatively connected to the movable sheave and is activatable to apply a force on the movable sheave.

摘要： System for converting mechanical energy such as ocean power into fluid power which is directed to energy conversion systems or other purposes. Included are fluid inflatable containers arranged to receive mechanical energy from a plunger mounted on a shaft, such that the flexible wall of the container forms a rolling lobe in response to changes in volume, enclosed within a drum, said shaft running axially through the drum and coupled to the drum by bearings so that the drum and shaft may move in relation to one another, a vane runs longitudinally on the drum and extending radially from an attachment point at the inner surface of the drum to the surface of the shaft. The mechanical energy is connected directly or indirectly to either the shaft or to the drum. Mechanical forces cause the plunger to press into the fluid inflatable container expelling fluid and creating fluid flow.
