This disclosure discloses various dispensation devices for dispensation of various volumes of content. For example, some of such content can include cream.

A continuously variable nozzle system includes a nozzle body (5) with an inlet and an outlet. A conduit is defined between the inlet and the outlet by a series connection of components which includes a flow meter (10). The flow meter (10) has a chamber (83) with internal helical splines (82) that are configured to interact with a spray liquid passing through the chamber (83) and create a cyclone-like effect. A sphere (52) is located inside the chamber (83) for free movement along a circular path (106). A sensor is located outside of the chamber (83) and configured to detect motion of the sphere (52) and generate an output (9) signal in response to detected motion.

An apparatus for use in marine platform jacking is disclosed herein. In one aspect, a jetting valve includes a valve body with a piston assembly disposed therein. The piston assembly is selectively operated to open and close the valve. A biasing member is coupled to the piston assembly. The piston assembly includes a first piston and a second piston. The dual pistons, in cooperation with the biasing member, allow the valve to self-seal thereby preventing entry of a fluid which is external to the valve.

A liquid saving device includes a liquid guide and a vortex adaptor. The liquid guide includes a primary recess, an indentation, and a plurality of primary pores. The vortex adaptor includes at least one air inlet structure, a trench, a gap and a center through hole. The plurality of primary pores is coupled to the indentation for receiving a first liquid stream to generate a same plurality of second liquid streams at respective ends. At least part of the plurality of primary pores have different lengths. A primary pore has a shorter length if the first primary pore outputs its corresponding second liquid stream with a larger deflection, and vice versa. The trench receives both at least one secondary liquid stream and air to generate a first aerated vortex. An elevated flow of the first aerated vortex with a spray-form liquid stream to generate a second aerated vortex.

The invention relates to a device for injecting a fluid, in particular a cryogenic fluid, the device comprising a fluid feed head and a fluid dispenser body, detachably mounted on said feed head, said feed head comprising a groove for circulating the fluid fed to said body, said groove being closed when the body is mounted on the feed head and said groove being open when the feed head and the body are detached from one another.

A control structure capable of adjusting water volume and controlling water supply contains: a body, a fixer, a valve stem, an adjuster, and a controller. The body includes a water outflow segment for connecting with a watering tool, an accommodation groove for accommodating the fixer and the valve stem. The fixer includes a flexible retaining rib, and the valve stem includes an inlet communicating with the water outflow segment, a fixing rib, an opening communicating with the inlet, and a guiding column. The guiding column has a seal ring. The fixing rib retains with the flexible retaining rib so as to limit a rotation of the adjuster along the body. The adjuster includes a threaded orifice screwing with a screwing section of the controller, an inflow aperture fitting with the guiding column, and a shoulder formed beside the inflow aperture. The controller is coupled with a water supply pipe.

A portable leaf blower comprises a blower tube, comprising an adjustable nozzle portion (200) which is reconfigurable between an air speed mode, in which the nozzle portion (200) is configured to expel the air from the blower at a relatively higher air speed and a relatively lower volumetric flow rate, and an air volume mode, in which the nozzle portion (200) is configured to expel the air from the blower at a relatively lower air speed.

A nozzle comprising: a main body having a sidewall, a first end and, a second end, wherein the main body has a central channel extending from the first end to the second end and at least one aperture extending through the sidewall distal to the second end and a retention means is positioned within the channel positioned between the second end and the at least one aperture; a collar having a lip disposed at a first end and a securement means disposed at a second end adjustably attached to the main body, wherein a cavity is formed between the main body and the collar and in a first position the lip creates a tight seal with the main body; a blocker positioned within the channel of the main body, wherein the blocker freely rotating about a central axis of the channel; and a means of axially retaining the blocker within the channel.

An applicator for delivering a glutinous substance comprises a first body portion, including an end-effector interface, extending from a base portion, a side cover to be removably coupled to the base portion, and a first cavity. A second body portion, having a second cavity intersecting the first cavity, extends from the base portion and is non-parallel to the first body portion. A tip portion, to be removably coupled to the second body portion, comprises a nozzle portion, a third cavity, communicatively coupled with the second cavity, an inner sleeve, having a splined outer surface, and an actuator interface, extending from the second body portion opposite the tip portion. The tip portion and the inner sleeve are interlocked when the inner sleeve is received inside the third cavity of the tip portion, such that the inner sleeve is prevented from rotating with respect to the tip portion.
