摘要:
A handheld fluid meter includes a cartridge valve controlling the flow of fluid through the handheld meter. The cartridge valve includes a valve cartridge and a valve stem disposed within the valve cartridge. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The overmolded stem tip is a compliant material. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

A nozzle for dispensing fluid includes a nozzle stem that controls the flow of fluid out of a dispensing end of the nozzle. The nozzle stem includes an overmolded stem tip on a reduced diameter portion of the nozzle stem. The overmolded stem tip is formed from a compliant material and includes a sealing portion and a tip cone extending from the sealing portion.

A variable flow poppet valve includes a first stage, a second stage, a bushing disposed in the second stage, and a cap configured to actuate the valve open. The first stage includes an inner valve plug having a head with a first tapered portion and a shaft extending downstream from the head, and a first stage spring disposed within the bushing and extending around the shaft. The shaft is attached to the cap to allow the cap to actuate the inner valve plug to the open position. The second stage includes an outer valve plug having an upstream portion and a second tapered portion extending downstream from the upstream portion. The bushing includes a shoulder, and the cap is configured to engage the shoulder to actuate the outer valve plug to the open position.

A hose reel includes a hose reel frame, a hose reel spool rotatably mounted on the hose reel frame for rotation about a rotational axis, a drive coupling attached to the hose reel spool and aligned with the rotational axis, a drive mount attached to the hose reel frame, and a drive module mounted on the drive mount that has a drive shaft connected to the drive coupling.

A series progressive divider valve comprises a valve body and pistons. A fluid inlet extends into the valve body. Stations are disposed in the valve body and extend from a first end to a second end; each station comprises piston stations extending through the valve body and a bypass station fluidly isolating the first end from the second end. The piston stations comprise a piston bore and a piston. The bypass stations comprise first and second fluid passages extending from the first and second ends to positions inside the valve body. Outlet bores extend into the valve body, and each comprises first and second sets of outlet bores. Porting forms passageways connecting the stations to each other and with the outlet bores such that when high pressure fluid is applied to the inlet the pistons reciprocates from the first end to the second end in sequence.

A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.
