A wave energy converter generates power from a wave-induced separation of a positively buoyant flotation module and a submerged negatively buoyant mass, using a rotating pulley to drive a power-take-off system.

An auto tensioner is mounted on a rotating shaft of an engine auxiliary device rotating about the rotating shaft by a power transmitted through a power transmission belt. The auto tensioner pivots about a pivot shaft. The auto tensioner has one side rotatably fastened to the pivot shaft and another side fastened to a driving member, and pivots about the pivot shaft in accordance with an operation of the driving member

A hydrostatic transmission assembly includes a main housing and a housing cap sealed to the main housing to form a sump wherein a pump and motor are rotatably disposed. A pump mount is located in the sump and engaged to the housing cap. The housing cap also includes a motor mount for an axial piston motor, and hydraulic fluid passages for connecting the pump to the motor. A pocket is located in the housing cap to rotationally support a swash plate for the pump.

A drive apparatus for a vehicle includes a hydraulic pump connected to two separate hydraulic motors by a center section. A brake puck is movable between a first position where it is disengaged from both hydraulic motors and a second position where the brake puck is engaged and provides a braking force to both hydraulic motors. A center section hydraulically connects the pump and motors and a charge pump is disposed on a separate face of the center section in a housing that both supports the charge pump and provides the gallery for the charged hydraulic fluid.
