A spray gun includes a valve cartridge configured to be axially installed and removed as a single piece. The valve cartridge includes the wear components of the spray gun. A trigger of the spray gun is configured to actuate a slider of the valve cartridge to control spraying by the spray gun. The trigger includes arms that are mounted to the spray gun by a pivot mechanism. The pivot mechanism can be disengaged from the arms to allow the trigger to slide between a spray position, where the trigger prevents forward axial movement of the valve cartridge, and a repair position, where the valve cartridge can move axially forward. The trigger also includes upper and lower portions that are movable relative to each other, such that the length of the trigger can be adjusted.

A modular fluid application device (10) includes a module base (12) and first and second fluid passageways extending within the module base and intersecting to form a nozzle fluid supply passageway. The modular fluid application device also includes a fluid outlet (22) formed on a nozzle mounting surface (24) of the module base fluidically connected to the nozzle fluid supply passageway, a base air passageway extending in the module base and an air outlet formed on the nozzle mounting surface fluidically connected to the base air passageway. A first module bank (14) is removably mounted on the module base and includes at least one first module having a first valve configured to control a flow of fluid in the first fluid passageway. A second module bank (18) is removably mounted on the module base and includes at least one second module having a second valve configured to control a flow of fluid in the second fluid passageway. The first module and the second module are mounted at an angle relative to one another.

A glue valve arrangement having a controllable, in particular electromagnetically operated metering member for the delivery of glue, having a main body with glue duct leading to the metering member, having a tubular glue line, with which glue originating from a separate glue source can be fed to the glue duct, having a rotary feedthrough, detachably fastened to the main body, for the articulated connection of the tubular glue line to the main body, and having a filter for the filtering of the glue. The invention is characterized in that the filter is assigned to the rotary feedthrough.

The invention relates to portable liquid supply device, mainly for water from central and other sources or for suspensions, for example pharmaceutical products and nutrient liquids. The invention can be used in household, outdoors, in the garden plots, in health care institutions, for example, for patients with dysphagia, as the source of purified drinking water or nutrient liquids, which go to a patient easily. Liquid supply device, includes raw liquid vessel, pressure generating means, liquid treating unit, comprising a lid, liquid supply means, liquid treating element and raw liquid inlet element, characterized in that is configured to supply treated liquid in portions from 5 to 100 ml, with velocity 0.5 to 10 ml/sec.

A ball joint connector is provided for linking a showerhead to a water supply pipe. The connector has an internal venturi that draws air into the connector to aerate water being provided to the showerhead. A flow control member is disposed in a fluid pathway connected to the venturi, preventing spraying or leaking out the air inlet, while reducing noise associated with the air induction.

An auxiliary element (1) for the local deposition of fluid for a fluid dispenser header (10), includes a hollow main body (2), including a hollow conduit (3) inside the main body (2), configured such that the fluid flows through its interior, comprising an opening for the inlet of fluid (5) coming from the fluid dispenser header at one end, and a fluid outlet opening (6) at the opposite end, a cavity (4) located between the wall of the main body (2) and the hollow conduit (3), configured such that residual particles of the fluid flow through its interior, at least one connecting mean (8) to the interior of the hollow conduit (3) to the residual particles cavity (4) and an opening (7) located on the main body (2), configured for the outlet of residual particles from the cavity (4).

A nozzle apparatus comprising: an inlet, an outlet, a filter disposed between the inlet and the outlet, and, a container; wherein the nozzle apparatus defines a first flow path for particles too large for said filter and a second flow path towards the outlet for particles small enough for said filter; and wherein the container is provided downstream of the first flow path. In this way the pressure on the container downstream of the first fluid path causes the debris to accumulate therein and the nozzle is less liable to blockages. The apparatus is of particular use as a sprinkler system.

In a method for operating a surface treatment installation, overspray produced in a coating booth is taken up by an air stream and carried to one or more one-way filter modules, in which overspray is separated. Once a limit loading with overspray is reached, a one-way filter module is exchanged for an empty one-way filter module. Depending on the nature and characteristics of the overspray, the one or more one-way filter module(s) may be chosen from a set of different one-way filter modules. A set of filter modules for use in a surface treatment installation is provided having various filter modules formed as exchangeable one-way structural units with a module housing and a filter unit. The module housings of the various filter modules have the same-connection module inlets and the same-connection module outlets and at least the filter units of two different filter modules are formed differently.

A method for handling a fluid includes separating the fluid into a liquid and a vapor within a container such that at least a portion of the vapor is disposed above the liquid, detecting a level of the liquid in the container, and actuating at least one valve to exhaust the vapor from the container to maintain the level of the liquid at or above a desired level. The at least one valve is communicatively coupled to a controller. The method further includes sending a signal from the at least one valve to the controller, and determining diagnostic data based at least in part on the signal.
