Abstract
A rocker valve comprising a rocker valve mechanism in a valve body. The mechanism comprises a single pivot arm to which first and second plungers are pivotally fixed to act in opposition. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports and having a first sealing region attached to a plunger head of the first plunger and a second sealing region attached to a plunger head of the second plunger. When the single pivot arm is pivoted relative to the valve body, a rotation of at least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member such that a lateral position of the plunger head is automatically adjusted by the flexible seal member to balance tensile forces in the flexible seal member around the plunger head.
