Abstract: A fluid metering valve comprises a valve body including an inlet opening and an outlet opening. A seal ring is installed within the valve body and defines an opening in communication with the inlet opening and the outlet opening. A valve assembly is arranged at least partially within the valve body and includes a valve stem and a piston moveably mounted to the valve stem with at least one degree of freedom. The piston is moveable into and out of sealing contact with the seal ring via the stem for selectively permitting fluid flow between the inlet opening and the outlet opening through the opening in the seal ring.

Abstract: A cleaning apparatus, including: a hollow handle with a first end and a second end; a spray manifold having an inlet and a plurality of outlets along a length of the spray manifold; and a plurality of wheels supporting the spray manifold; wherein the inlet of the spray manifold is connected to the first end of the handle via a swivel coupling assembly, such that the spray manifold is rotatable in two orthogonal directions relative to the handle; and wherein the second end of the handle is configured to receive a fluid.

Abstract: An aerating nozzle tip comprises a housing having a central axis, an inlet, an outlet, a plurality of passages disposed around the central axis between the inlet and the outlet, and a circumferential aspirator disposed between the inlet and the outlet.

Abstract: A valve comprises a housing, a handle for opening and closing the valve, a handle release that is engagable with the housing to prevent movement of the handle relative to the housing, and that is disengageable from the housing to enable movement of the handle relative to the housing, and a lock for maintaining the handle release engaged with the housing to prevent movement of the handle relative to the housing.

Abstract: A valve assembly for a liquid containing tank or the like, having a vortex breaker within the tank of liquid, and affixed to an external valve. The valve has a discharge port and a valve body with an outer member which allows the flow of liquid and a concentrically-spaced inner member provided with upper and lower seals to prevent the leakage of the liquid and allow uniform closure of the valve. The inner tubular member is movable vertically such as with a screw thread and associated handle, from a closed to an open position to allow flow of the liquid from the tank to a discharge port.

Abstract: A fluid coupling device employs a male spherical member with a fluid receiving bore and a female housing. The spherical member abuts two axially spaced Teflon ring seats between the member and the housing in the housing chamber. The ring seats reduce friction between the member and the housing and axially retain the member in the housing with no metal to metal contact. A first O-ring provides fluid sealing between the spherical member and housing inner wall in the chamber. A hose receiving nipple member with a fluid receiving bore has a threaded concave end with a peripheral region that engages the first O-ring to hold the O-ring against the spherical member, one of the ring seats and housing chamber wall to seal the interface between the spherical member and housing. The nipple member has a flange which abuts the housing to limit squeezing action on the O-ring to ensure sufficient contact of the O-ring and mating surfaces to obtain a good seal without creating excessive friction loads.

Abstract: An adaptor is for a rising disc valve which has a handle for rotating a stem in a housing bore having a shoulder and which displaces a disc valve member which seals against a frusto-conical housing seat spaced from the shoulder. The adapter has a piston threaded to the stem by an attachment member. The piston has a cylindrical shank to which a Teflon ring seal is secured. The piston includes a steel valve disc member opposite the attachment member end for engaging the frusto-conical seat. A stack of Belleville steel springs is between the disc member and the ring seal. An interface ring is between the springs and the ring seal. As the disc member is seated in its valve seat, a ring at the attachment member abuts the shoulder. The attachment member can no longer axially displace and compressively loads the springs as the disc member is further axially displaced to the valve closed state.

Abstract: A retrofit automatic temperature controlling apparatus and kit is attached to a prior art steam-cold water mixing valve assembly to produce mixed cold water and steam as hot water at a controlled temperature. An adjustment screw is added to the prior art valve assembly to limit the displacement of a steam poppet valve which is opened by a retrofitted piston. Cold water is redirected to a retrofit temperature control assembly having a mixing chamber for receiving the cold water. A water and steam receiving conduit terminates in the mixing chamber and has fluid isolated sections for receiving steam and cold water with a sleeve valve member for selectively coupling the steam and cold water sections to the mixing chamber. The sleeve valve member is operated by a temperature sensing device in the outlet hot water chamber. A disc member separates the mixing chamber and outlet hot water chamber with small passages which promote mixing.

Abstract: A trigger having a pawl operates a nozzle valve via a valve stem in a nozzle barrel bore. A spring in the barrel bore normally biases the valve closed. A toothed ratchet lever is pivotally resiliently secured to a trigger guard which protects the trigger from accidental activation. A ratchet tooth in an array of teeth on the lever engages the pawl to hold the trigger in a selected spray position of the valve, the teeth being normally biased disengaged by a second spring. The teeth each have a sharp crest which digs into the trigger in response to the spring bias on the valve stem overcoming the disengagement bias on the ratchet from the second spring. The nozzle is closed by squeezing the trigger to release the ratchet and pawl engagment such that the ratchet lever is pivoted to a disengagment position by the second spring. The assembly comprises metal components in contact with hot fluid but which are thermally insulated with an outer casing spaced from the components by an air gap.
