    摘要： The pump comprises a chamber divided into a lower cavity occupied by the fluid and an upper cavity at atmospheric pressure. A flexible ring piston sealingly runs in the chamber and is inserted in a slidable way on a stem valve, with which it co-operates to enable or interrupt the outward flow of the fluid. The piston has a tapered section at its lower end, which engages by friction in a corresponding tapered groove of the stem valve to allow delivering of a fine mist with a very low delivery pressure also.

    摘要： Pump that can be applied on a container and manually operable to deliver or dispense a liquid in an atomized form. The pump comprises a hollow stem for liquid delivery or dispensing, on which a sealing gasket is mounted and downward urged by a spring. A groove communicating through holes with the cavity of the stem is provided on the lower end of the latter. The gasket, normally sealing on the stem below said groove, when upward moved upon operation of the pump, has its lower edge suddenly bent inwardly of the groove, when arriving thereat, thus suddenly and completely communicating the passage of the pressure liquid to said holes of the stem.

    摘要： The present invention relates to a contents dispensing pump which is coupled to a container (V) for accommodating the contents therein and dispenses the contents, comprising: a pump main body (10); a pump upper body (20); a pump inner body (30); a dispensing valve (40); and an elastic member (50). The pump upper body (20) is coupled to the upper side of the pump main body (10) so that a pumping operation is made by an up and down movement with respect to the pump main body (10). The pump inner body (30) has a bowl shape with the middle thereof formed to be dented so that an inlet valve plate (70) is integrally formed on the lower surface. The dispensing valve (40) is coupled to the upward side of the pump upper body (20), and has, formed therein, a valve protrusion wheel (41) for opening and closing the content outlet (23). The elastic member (50) is positioned between the upper lateral surface extension piece (33) and the lower lateral surface extension piece (34) of the pump inner body (30) so as to draw the pump inner body (30) and simultaneously elastically support the pump main body (10) and the pump upper body (20).

    摘要： In one embodiment, a self-cleaning nozzle comprises a nozzle body, a sleeve surrounding a proximal end of the nozzle body, a pillar disposed within the nozzle body and a spring. The nozzle body may have a hollow cylindrical interior. The nozzle body may include an orifice formed in a distal end of the nozzle body, a shoulder formed on a proximal end of the nozzle body, and a first bearing surface on an outer lateral face of the shoulder. The sleeve may include a second bearing surface on an inner face of the sleeve and a retaining lip formed at a distal end of the sleeve. The retaining lip may define a distal end of an annular space between the sleeve and the nozzle body. The shoulder may define a proximal end of the annular space. The pillar may have a distal tip configured to interface with the orifice, thereby forming a liquid seal. The spring may be captured within the annular space, thereby biasing the distal tip of the pillar into contact with the orifice.

    摘要： A finger spray pump for spraying a medium, which includes a finger-actuated pump head, an outlet nozzle and a pump chamber which includes an inlet valve and a pump piston which can be moved by moving the pump head. The medium passes through a medium path between the pump chamber and outlet nozzle, additionally, the pump piston forms, in cooperation with a piston rod, an outlet valve and the pump piston can be moved with respect to the piston rod counter to the force of a first spring for actuating the outlet valve, the piston rod can be moved counter to the force of a second spring. Additionally, both springs are arranged outside of the medium path. In order to obtain a compact design, both springs are arranged at a distance from each other, axially independent from the pump position.

    摘要： A trigger-type liquid dispenser includes valve member, which is provided in flow path to control liquid to flow in direction in flow path. Valve member includes intake-side check valve, which permits flow of liquid from container side to pump side and prevents flow of liquid from pump side to container side, and discharge-side check valve, which permits flow of liquid from pump side to nozzle side and prevents flow of liquid from nozzle side to pump side. Discharge-side check valve is formed in umbrella shape that is elastically deformable freely in radial direction and has outer circumferential end configured to contact inner circumferential surface of flow path, with contact force of outer circumferential end with respect to inner circumferential surface of flow path being distributed non-uniformly in circumferential direction.

    摘要： A pump dispenser includes a dispenser head rotatable relative to a locking ring for a lock-down feature during shipment. The lock-down feature requires a greater torque to initially rotate the dispenser head from the lock-down position, and a lesser torque to further rotate the dispenser head to a use position. The lock-down feature incorporates an interference between the dispenser head and locking ring, either inside the dispenser head, on an outer periphery of the dispenser head, or between threads connecting the dispenser head and locking ring.
