ABSTRACT:
A hand-operated pump for dispensing a fluid from a container includes a body containing a pumping chamber having an inlet and an outlet. A piston is reciprocably mounted in the pumping chamber, the piston having a convexly contoured outer end surface. A trigger pivotally mounted to the body has a plurality of triangular supports co-joined to form a tapered socket receiving the outer end surface of the piston. A channel-defining insert is received in the outlet, the insert having a centrally situated, forwardly facing, fixed protuberance. An elastic, cup-shaped member secured at its periphery to the body has a central aperture situated in contact with and closed by the fixed protuberance. The central aperture of the cup-shaped member is a cavity in the center of the interior surface of the member extending only partway through the member, at least two depressions on the exterior surface of the member spaced from each other yet each intersecting the cavity, and a swirl chamber situated between and connected to the depressions.
