Abstract
The invention provides a pump assembly comprising an actuator lever, a supporting structure, a pump comprising a pump member moveable by actuation of the actuator lever, and an actuator for moving the actuator lever. A first stationary pivoting joint is formed between the actuator lever and the supporting structure, and a second floating pivoting joint is formed between the actuator lever and the pump member allowing the pump member to float relative to the actuator lever, the floating pivoting point providing a constant-length actuator arm defined between the first pivoting joint and the second pivoting joint.
