PUMP ASSEMBLY COMPRISING ACTUATOR SYSTEM
First Claim
1. A pump assembly (600) comprising:
- an actuator lever (630),an actuator comprising an actuator member (640) for moving the actuator lever,a supporting structure (620),a pump (150, 300) comprising a pump member (151) moveable by actuation of the actuator lever,a first pivoting joint (633) formed between the actuator lever and the supporting structure, anda second pivoting joint (643) formed between the actuator member and the supporting structure,wherein the actuator lever and the actuator member are coupled to each other by a coupling joint (650) arranged between the first and the second pivoting joint,whereby rotation of the actuator member in a first direction causes the actuator lever to rotate in an opposite second direction.

Abstract
The invention provides a pump assembly comprising an actuator lever, an actuator for moving the actuator lever, a supporting structure, a pump comprising a pump member moveable by actuation of the actuator lever, a first pivoting joint formed between the actuator lever and the supporting structure, and a second pivoting joint formed between the actuator and the supporting structure. The actuator lever and the actuator are coupled to each other by a coupling joint arranged between the first and the second pivoting joint in such a way that rotation of the actuator in a first direction causes the actuator lever to rotate in an opposite second direction. By providing an actuator system comprising two actuator elements linked to each other by a coupling joint ensuring counter rotation of the two members, a system is provided which can be made less susceptible to the influence of acceleration.
