A transmission for a vehicle includes a fixed displacement pump operable to produce a high pressure flow and a fixed displacement motor. A fluid flow path is disposed between the pump and the motor. The fluid flow path is integrated into a housing containing at least one of the pump and the motor. A single control valve controls the direction and the speed of the motor.

A sprue structure is specifically designed to facilitate the rapid filling of molded polystyrene patterns with molten metal. It comprises a down sprue and parallel columnar members that are connected to the down sprue. The flow of molten metal is initially downward through the first columnar member and then it reverses direction to flow upwardly through second and third columnar members so that the patterns to be cast receive molten metal as it travels upwardly through the second and third columnar members. This decreases the amount of pyrolyzation products that could otherwise flow through in-gates and into the patterns to be cast.
