Abstract (en)

A mechanism (150) for a pump (100) which includes a pump body (120) having protrusions (122). The mechanism (150) includes a movable basket (130) movable between a first position and a second position. The one or more protrusions (122) bias the movable basket (130) in one of the first position and the second position. The mechanism (150) includes a switch bar (140) which allows selective locking of the protrusions (122). The switch bar (140) moves between a locking position (P1) and an unlocking position (P2). The mechanism (150) is characterized in that the actuation of a trigger (160) moves the switch bar (140) between the locking position (P1) and the unlocking position (P2). And, in the unlocking position (P2) of the switch bar (140), the protrusions (122) is unloaded such that the movable basket (130) is movable between the first position and the second position.
