초록 ▼

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.

대표청구항 ▼

[ What is claimed is:] [1.] A finger-operable pump comprising:a pump body defining a chamber and having an inlet opening and outlet opening;a non-return valve located at said inlet opening;an actuating plunger projecting from said chamber for reciprocatable movement between an elevated, unactuated, rest position and a lowered, fully actuated position, said plunger having upper and lower plunger portions together defining a discharge passage establishing communication between ambient atmosphere and said chamber, said plunger lower portion defining a valve seat at said discharge passage;a plunger return spring acting between said pump body and plunger lower portion for biasing said plunger relative to said pump body toward said rest position;a piston carried by said plunger in said pump chamber in sliding and sealing engagement with said pump body for accommodating movement relative to said plunger between (a) a closed position sealed against said valve seat to occlude said discharge passage, and (b) an open position spaced from said valve seat; anda piston return spring acting between said piston and plunger upper portion for biasing said piston toward said closed position, said piston return spring including a post which is oriented for being subjected to compressive loading and which is resiliently bendable.
