Abstract: A liquid sprayer is provided. This liquid sprayer comprises a bottle having an opening and a sprayer housing attached to the bottle. This sprayer housing includes an electric motor, a voltage source for powering the electric motor, a pump driven by the motor, a switch for completing an electrical circuit, a nozzle mechanism attached to the sprayer housing for spraying a liquid. The liquid sprayer also comprises a venting mechanism. This venting mechanism comprises a vent housing having an inner surface and an outer surface, and a translating piston disposed in the vent housing.

Abstract: A method for modifying the swirl motion of a liquid in the swirl chamber of a nozzle, and a swirl generator for nozzles. Such nozzles are used in industrial burners, oil burners and installations for cleaning flue gas and spray-drying food. The invention provides a method and nozzle for adjusting the man droplet diameter at a constant volume flow rate on maintaining the droplet spectrum constant in case of adjustment of the volume flow rate. Partial flows are distributed across supply channels which differ in terms of their cross sections at their point of connection with the swirl chamber. When the partial flows are constituted by the sum of cross-sections of the channels branching off the corresponding flow. Thus, the sums of the cross-sections at the connection point with the swirl chamber are different.

Abstract: A collapsible pump chamber is provided which includes several functional elements of a pump device. For example, the collapsible pump chamber may be a bellows which includes a functional element of an outlet valve, a functional element of a biasing feature, and a functional element of a spin chamber. Consequently, a functional element of all of the downstream functions are incorporated into the bellows. This can significantly reduce costs due to reduced tooling and assembly, for example. In contrast, there are no upstream components incorporated into the bellows which enables the upstream or inlet end of the bellows to be wide open. This wide open upstream end of the bellows makes molding easier.

Abstract: A trigger operated dispensing device for the discharge of fluids, particularly in a spray. The device comprises a housing including a trigger, which actuates a flexible pump. The flexible pump has an inlet accepting the fluid and an outlet end through which the fluid passes going to the discharge. The flexible pump, preferably of bellows type, is situated in line with and just adjacent to the discharge wherein rotational motion of the trigger results in rotational compression of the pump chamber. In a particularly preferred embodiment, the flexible pump further includes mechanical structure for imparting a radial momentum to the fluid prior to discharge.

Abstract: The invention relates to improvements in or relating to a desuperheater for controllable injection of cooling water in a steam or gas line (17), said desuperheater device including an insertion tube (1) extending inside the pipe (17), said tube (1) having a conical outlet nozzle (7) with a valve body (5) movably arranged in a hole (2) in the insertion tube (1) such as to form a regulating port (4). The hole (2) in the insertion tube (1) opens out into a rotation chamber (3) with the centerline (10) of the hole and the centerline (11) of the rotation chamber (3) disposed relative each other at an angle deviating from 90.degree. by an angle .alpha., and where the angle .alpha. is greater than 0.degree. but less than 30.degree..

Abstract: A dispenser body comprises an upper portion and a lower portion vertically extending from the upper portion. A piston is substantially L-shaped, comprising a horizontal nozzle fixed to the upper portion and a piston body located at the lower portion. A cylinder is coupled with a swingable trigger and located at the lower portion; it can reciprocate when the trigger is squeezed and released. An inlet conduit is formed within the cylinder, whereas an outlet conduit is provided within the piston. A slit is cut in the front section of the lower portion. Thanks to this slit, the lower portion is resiliently fitted in a bottle cap and, thus, connected thereto. The rear end of the trigger and the nozzle can pass through this slit. The proximal end of the bottle cap is held between the lower edge of the rear section of the lower portion and an engagement member formed on the lower portion.

Abstract: A dispensing apparatus comprises a pressurised dispensing container (3), a housing (2) for the container defining a bore, the container having a body (50) which is axially slidable in the bore, the container having a collapsible metering valve (8) located at a first end (6) of the body for dispensing metered quantities of fluid and actuated by axial depression of a valve stem (9) defining a dispensing flowpath, a valve actuator (11) fixedly connected to the housing at a corresponding first end (7) thereof and defining a further dispensing flowpath for product fluid dispensed through the stem, and trigger means (30) operable to urge the container body axially towards the first end of the housing such that the valve stem is depressed by relative movement together of the valve and actuator and thereby dispensing a metered quantity of fluid, wherein the container body defines a chamber (4) and the container includes means (5) dividing the chamber into a product fluid reservoir (25) communicating with the valve an

Abstract: In an eddy current brake for controlling quantitative flow in a water line and with a brake housing in the shape of lying frustum of a cone with an outlet opening in the narrow end and an inlet opening downwardly on the large end face there is disposed a guide vane opposite the inlet opening within the housing, said guide vane being rotatable about the axis of the housing by means of an exterior adjustment lever between a position in which it closes the inlet, and a position in which it is disposed completely outside the inlet region and thus allows free flow. In intermediate positions the guide vane deflects the in flowing stream of water toward the frusto-conical wall so that the water, when the pressure head exceeds a certain valve, is caused to rotate about the axis of the housing to produce the desired brake effect. This effect can be varied by adjustment of the guide vane. Its deflecting effect permits the inlet spout and outlet spout of the brake housing to be disposed in elongation of each other.
