A high-pressure pump has a metering valve and a valve stopper. The stopper has a regulation portion which an end surface of the valve is brought into contact with. An outer diameter of the regulation portion is equal to an outer diameter of the outer peripheral surface of the valve. A cylindrical sleeve is disposed around the regulation portion. When the end surface of the valve is in contact with the regulation portion, the sleeve covers a tapered surface of the valve.

A high pressure relief valve includes a nozzle that is received within an internal bore of a valve housing. The nozzle has a nozzle body with a bore defined by an outlet bore inner diameter that is less than an inlet bore inner diameter. The nozzle body has a nozzle face defined at the outlet end, and is defined between the outlet bore inner diameter and an outlet bore outer diameter spaced radially outwardly of the outlet bore inner diameter. The nozzle body includes a coupling feature held fixed relative to the nozzle body such that the coupling feature is not moveable relative to the nozzle body. The coupling feature is configured to couple the nozzle body to the closure sleeve that surrounds the outlet end. At least one retaining feature prevents the coupling feature from being uncoupled from the closure sleeve.

Various embodiments of valve assemblies are provided for use in connection with the fluid systems of machines such as engine-powered machines. The valve assemblies may be used for performing fluid refill operations, fluid evacuation operations, fluid purge operations, and other types of fluid operations in connection with machine maintenance.

The present application provides a water distribution system with a flow of water therethrough. The water distribution system may include one or more water lines, a number of flow control passages in communication with the one or more water lines, a number of flow controllers with a number of preset flow rates positioned about the flow control passages, and a number of flow control valves positioned about the flow control passages such that opening one of the flow control valves allows the flow of water to flow through one of the flow control passages with the preset flow rate.

A backflow prevention assembly for global use with dispensers requiring a variety of backflow prevention devices based on regulatory standards is provided. The assembly includes a housing comprising first and second housing members and including quick connector attachments extending therefrom. The quick connector attachments are non-threaded members configured to be attached to the various measurement and types of connections found throughout the world. A cover is provided for venting purposes to reduce the backflow siphoning forces or pressure, which causes the backflow of a product chemistry. Furthermore, a backflow prevention device is configured to be fluidly coupled to the housing of the present invention to provide for one way flow and the prevention of backflow of a product chemistry into a water supply. The flow control may be selected based on the regulatory standards of the location used.

Provided is a roll over fuel-vapor valve is provided including a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between the inlet port and the outlet port and being displaceable between an open position and a closed position the hosing further comprising a fluid flow channel extending along a top portion thereof and having a first end and a second end, wherein the outlet port extending into the channel such that in the open position fluid flow is facilitated between the valve inlet port and the channel.

A method for transporting a viscous fluid through a heat exchanger line that includes transporting a viscous fluid through a connecting piece with an excess pressure release component, where the excess pressure relief component separates an interior of the connecting piece from a discharge line in the connecting piece, and is fixed to an edge of the discharge line, mixing a fluid flow in a region of the excess pressure relief component using a mixing element disposed in the interior of the connecting piece and causing the excess pressure release component to release at least a portion of the fluid through the discharge line when the pressure of the fluid is equal to or greater than a preset excess pressure.

Disclosed is a device that includes a choke valve. The choke valve may include a generally tubular throttling member having a sealing shoulder disposed in an inner volume of the throttling member, a plurality of openings configured to flow a fluid between the inner volume of the throttling member and an outer volume of the throttling member, and a flow-impeding recess disposed between the sealing should and the plurality of openings in the inner volume of the throttling member. The choke valve may also include a valve member disposed at least partially in the inner volume of the throttling member.

A system for collecting and accumulating excess water from one or more in-building sources and delivering it to one or more flushing toilet tanks and possibly also to one or more other in-building consumption devices, such as washing machines or utility faucets. The in-building sources may include any of condensate from an air conditioner, cool water in a hot water supply pipe emerging during initial flow, treated waste water and collected rain- or snow water. At the heart of the disclosed system is an accumulation tank of large capacity, having at least two inlets and at least one outlet. One of the inlets is connected to the main water supply system and includes a valve, configured to let fresh water flow into the main tank whenever the level of the water stored therein falls below a given height. Each outlet is connected to a conduit, conveying water from the accumulation tank to one or more toilet flushing tanks, as their only source, and possibly to other water consumption devices.
