Abstract: An all-polymer reciprocating pump (100) is contemplated. The pump body (160) receives a sliding insert (170) that may be locked in a down position to minimize the extension and profile of the actuator (120) while the pump (100) is not in use (e.g., for purposes of shipping in e-commerce). Projections (171) slide within guides (181) formed on an insert housing (180). Even in this down locked position, minimal compression is applied to the biasing members (130) so as to avoid fatigue, wear, and/or failure of the plastic components.

Abstract: A dispensing device dispenses a liquid held in a container. The device includes an engagement portion for the mutual engagement of the device and the container. Drawing and dispensing means draws the liquid from the container to dispense it. A main operating body operates the drawing and dispensing means through pressure exerted along a pressing direction. The main operating body moves with respect to the engagement portion, when subjected to pressure, between a rest position and an activating position. A dispensing nozzle is fixed to the main operating body and provided with a dispensing duct suited to dispense the liquid. The dispensing nozzle is switched from the main operating body, through a rotary movement, between a dispensing position and a non-dispensing position. Constraining means prevents the movement of the main operating body along the pressing direction when the dispensing nozzle is in the non-dispensing position.

Abstract: A liquid dispensing pump for a portable container in which the pump piston is disposed for lost motion in the pump cylinder between the plunger rod and a discharge valve carried by a stem affixed to the plunger rod and extending through the piston. The piston has upwardly and downwardly presented elastomeric skirts of which the lower skirt seats against the discharge valve on the piston upstroke and the upper skirt seats against a venting valve at the termination of the upstroke. Both the discharge valve and the venting valve exert an expanding action on the respective piston skirts incident to their seating relation with the skirts under the resilient pressure of the pump spring, to counteract any shrinking tendency of the skirts, and means are provided for limiting the expansion of the skirts. The upper and lower ends of the piston are symmetrically arranged to permit reversal of its position in the pump.

Abstract: A pump for delivery of gas-liquid mixtures adapted to be connected to a container for a liquid comprising: suction means adapted to be reciprocated between a first rest position and a second position so as to collect the liquid from the container; a mixing chamber in communication with the suction means so that when the suction means are moved from a first position to a second position, the liquid is collected from the container and conveyed into a mixing chamber; elastic means adapted to displace the suction means back in the first position after that the suction means are moved from a first position to a second position. The elastic means define a variable volume gas chamber in communication with the mixing chamber so that, when the suction means are moved from a first position to a second position, the gas is conveyed into the mixing chamber and a gas-liquid mixture is formed in the mixing chamber.
