ABSTRACT:
A finger-operable pump includes a pump body, a non-return valve, and an actuating plunger. A plunger return spring biases the plunger toward an elevated, rest position. A piston is carried by the plunger and is movable relative to the plunger between a closed position sealing a discharge passage in the plunger and an open position in which fluid can flow from the pump through the plunger discharge passage and out of the pump. A piston return spring is provided between the piston and the plunger for biasing the piston toward the closed position, and the piston return spring includes a post which is resiliently bendable.
