摘要:
L'invention concerne une valve doseuse pour récipient aérosol, présentant une face interne destinée à être placée à l'intérieur du récipient aérosol et une face externe destinée à être placée hors du récipient aérosol. La valve est munie: d'un corps de valve (1) présentant une chambre interne (17) pouvant être mise en contact soit avec la face interne de la valve, soit avec la face externe de la valve, d'une tige (41) munie de moyens de fermeture (42) et placée en partie à l'intérieur de la chambre interne (17) mobile entre deux positions, à savoir une position fermée dans laquelle la chambre interne (17) est en contact avec la face interne de la valve, mais isolée de la face externe de la valve, et une position ouverte dans laquelle la chambre interne (17) est en contact avec la face externe de la valve, mais isolée de la face interne de la valve, d'un réservoir (R) pouvant être rempli lorsque la tige (41) est en position fermée et vidé lorsque la tige (41) est en position ouverte. Conformément à l'invention, le réservoir (R) est situé du côté de la face interne de la valve, hors du corps de valve (1), le réservoir (R) est en contact avec la chambre interne (17) du corps de valve (1), et le réservoir (R) est constitué d'au moins une membrane souple (2).

The present invention pertains to the field of home appliances and refers to a delivery valve stem (1) more specifically intended to be used in laundry machines provided with a reservoir (5) for bulk material storage and delivery, wherein said valve flow delivery is not aligned with its displacement axis, since it comprises a predominantly radial sealing system that contributes to clean surfaces in contact with fluid, thereby promoting reduction in the production of residues from washing products, which may be detached and reach the fabrics stored inside the equipment, damaging them and/or causing several inconveniences.

A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. The switching valve may be incorporated into the body of a high pressure nozzle. In one embodiment a mid portion of the valve body has at least one passage therein leading from a central axial bore to first and second external ports. A poppet member received in the central axial bore directs fluid flow in a first position to the first external ports. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the second set of external ports. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.

A valve (10) for dispensing a flowable product from a container includes a mounting cup (14). The mounting cup includes a bottom wall (24) having a central portion (26) defining a seal-mounting opening (28) through which a seal (18) and a stem (16) extend. An external seal bead (46) of the seal overlies an upper end of the central portion (26). The upper end of the central portion is disposed at or below a plane extending transverse to a central axis of the mounting cup and defined by a juncture of a sidewall (22) and an annular sidewall-bottom transition portion (66) of the mounting cup (14).

The invention relates to a swiveling nozzle for unclog hoses particularly designed for accessing pipes with interruptions in their course. It has a head (1 ), integral with a swiveling spherical segment (2) inside a spherical bushing (3) provided with a groove (4) in which a neck (6) connecting the spherical segment (2) with the head (1 ) works, and said spherical segment (2) being provided close to its swivel center (8), coinciding with its geometric center, with a guiding element (9) acted on by transmission means from an actuator (13) which in turn can axially move inside a cylindrical bushing (5) integral with the spherical bushing (3) opposite to the head (1), against the tension of a spring (14) and when the water under pressure accesses the nozzle. In each maneuver in which water is supplied to the nozzle the orientation of the head (1 ) thus changes.

A dispenser (100, 400) includes a depressible thermal tip (102, 402) and a housing (104, 410) having a reservoir (114, 422) for containing a product, such as a cosmetic product or a medicinal product. The depressible thermal tip (102, 402) comprises a thermal applicator (106, 404) displaceable between open and closed positions. The thermal applicator (106, 404) may be depressibly coupled in a collar (108) fixed to the housing (104), or the thermal applicator (404) may be depressibly coupled in a button (406) depressibly coupled in a collar (408) fixed to the housing (410).

The invention relates to a faucet device for dispensing of a pressurised fluid, for ex- ample water, comprising an outlet member, preferably a spout, and a shut-off mechanism, said outlet member having an initial position (A) in which the flow of fluid through the outlet member is shut off, said shut off mechanism being arranged such that said outlet member, when subjected to an external force in a certain first direction enters a self-closing open position (B) allowing flow through the same, and when said force is no longer applied said outlet member returns to its initial position by self closing means, wherein said shut-off mechanism (20; 110; 210; 310) further is arranged such that when the outlet member (10; 100; 200; 300) is sub- jected to a force in a second direction different from said first direction it is releas- ably held in a certain position (C) allowing flow through the same. The invention also relates to a method for dispensing of pressurised fluid by means of a faucet device.

A changeover valve (100) comprises a first valve member (20) and a second valve member (50). The first valve member (20) has an aperture (28). The second valve member (50) has first and second apertures (54, 58). The first valve member (20) is movable relative to the second valve member (50) for selective alignment of the first valve member aperture (28) with one or other of the apertures (54, 58) of the second valve member (50). The valve (100) also has a ramp and follower means (29, 62) for automatically moving the valve members (20, 50) away from the one another during changeover movement of the first valve member (20) relative to the second valve member (50) so that wear on the surfaces of the valve members (20, 50) is minimised.
