Abstract: A temperature management system for a fuel cell unit includes a pump, a valve fluidly connected to the pump, and defining an inlet, and first, second and third outlets, a heater, a heat exchanger, a radiator. The valve is selectively adjustable between at least first, second and third configurations. In the first configuration, the valve is configured to direct fluid along a first path defined at least by the first outlet, the heater, the fuel cell unit, the pump, and the inlet. In the second configuration, the valve is configured to direct fluid along the first path and along a second path defined at least by the second outlet, the heat exchanger, the pump, and the inlet. In the third configuration, the valve is configured to direct fluid along a third path defined at least by the third outlet, the radiator, the fuel cell unit, the pump, and the inlet.

Abstract: A CVT pulley includes a shaft having disposed thereon, a first and second sheave, and a spider. A spring biases the sheaves away from one another. The axially moveable second sheave is disposed axially between the axially fixed spider and the first sheave. A plurality of centrifugal weights, connected to either the spider or the second sheave, have a portion that moves radially outward with rotation of the shaft. The axial distance between the spider and the second sheave depends at least in part on the radial position of the portion which depends on the rotational speed. At least one cylinder is adapted to receive fluid. At least one piston, rotatable with the shaft, is adapted to move in the at least one cylinder in response to fluid being received therein, thereby selectively exerting force on one of the sheaves towards the other. CVTs and vehicles are also disclosed.
