Abstract
A fluid pressure controlling unit including a housing defining at least one substantially fluid tight chamber having first, second and third ports. An arm is disposed, at least in part, in the at least one substantially fluid tight chamber and is capable of being moved between positions which close either the first or the second port. A spring biases the arm to close either the second port or the first port (preferably the second port). An electrically actuable device is capable of moving the arm to close the first port. When the arm closes the second port, the first and the third ports are in communication via the chamber(s), and, when the arm closes the first port, the second and the third ports are in communication via the chamber(s).
