A protection device for protecting the potable water from contamination caused by backflow, comprises a housing with a potable water inlet, a first funnel, which is arranged at a distance to and aligned below the potable water inlet, and a second funnel, which is arranged at a distance to and aligned below the first conical funnel, and via which the water can be drained. An opening in the housing is formed for the discharge of the backflowing water, to which the back-flowing water can flow between the first and the second funnel.

A decorative air gap cap cover is disclosed. An example embodiment can include: a hollow decorative shell configured with upper and lower interior regions relative to an internal ridge, the internal ridge configured to rest on an upper surface of a ring gasket installed around an air gap cap, the air gap cap being captured within the upper and lower interior regions of the hollow decorative shell; a fluid channel within the hollow decorative shell configured with an entry opening above the internal ridge and an exit opening below the internal ridge, the exit opening terminating at an exit port of the hollow decorative shell; and a top vent hole providing an air channel between the upper interior region and the exterior of the hollow decorative shell. An embodiment can also include an auxiliary fluid channel configured with an entry opening below the internal ridge and an exit opening below the internal ridge.

A one way valve cartridge for a flow assembly includes a housing having an axial aperture formed therein. A leading ring is coupled to the housing. A piston is disposed in the housing and is in sliding relationship with the leading ring. The piston is configured to reciprocate between a closed position to seal the axial aperture and an open position to permit a flow of fluid through the axial aperture. A spring urges the piston into the closed position to seal with the housing.

A fully serviceable frost proof mixing hydrant for supplying water at various temperatures to the exterior of a building. The mixing hydrant includes hot and cold water inlets and a chamber in which the water is mixed based on the position of a cammed wheel acting on a pair of poppets. These poppets act as temperature regulators and check valves to prevent cross-flow leakage and/or contamination. The mixing hydrant includes an inside tube or flow sleeve for delivery of water to an outside body tube in communication with a spout on the head of the hydrant. The flow from the inside tube to the outside body tube reduces turbulence and provides a better outlet flow from the spout. Flow control and temperature control are independent allowing the user to set the flow as desired then adjust the temperature as desired without affecting the flow.

An electromagnetic valve for a hydraulic system for an automatic transmission of a vehicle. An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.

A decorative air gap cap cover is disclosed. An example embodiment can include: a hollow decorative shell configured with upper and lower interior regions relative to an internal ridge, the internal ridge configured to rest on an upper surface of a ring gasket installed around an air gap cap, the air gap cap being captured within the upper and lower interior regions of the hollow decorative shell; a fluid channel within the hollow decorative shell configured with an entry opening above the internal ridge and an exit opening below the internal ridge, the exit opening terminating at an exit port of the hollow decorative shell; and a top vent hole providing an air channel between the upper interior region and the exterior of the hollow decorative shell. An embodiment can also include an auxiliary fluid channel configured with an entry opening below the internal ridge and an exit opening below the internal ridge.

A turbulence reducer may be integrated in the vacuum breaker prevents leakage during use of the hydrant by reducing turbulence acting on the vacuum breaker poppet. Additionally, the user is able to service all aspects of the hydrant from outside the building

A reduced pressure treatment system includes a porous pad positioned at a tissue site and a canister having a collection chamber, an inlet, and an outlet. The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.
