<p>An apparatus is provided for sequentially actuating a pair of valves used to control a flow of brake fluid in a vehicle. Each valve is yieldably biased toward a normal position. The apparatus includes an actuation member that is tiltable in response to movement of a piezoelectric member to accomplish sequential operation of the valve pair, the actuating member being tiltable during a first adjustment stroke counter to the force of the first valve spring about a first axis of rotation defined by a bearing point fixed to the housing and by a compression spring in order to actuate the first valve and move the first tappet to a selected position. The actuating member is also tiltable during a second adjustment stroke counter to the force of the compression spring about a second axis of rotation defined by the bearing point fixed to the housing and by the moved first tappet in order to actuate the second valve.</p> |
