A variable device for regulating the outlet pressure of a fluid from a valve body, includes a pressure-sensing chamber having a wall formed by a resilient self-restoring diaphragm which is responsive to pressure in the chamber. A valve element connected to the diaphragm controls flow into the chamber. Increased pressure in the chamber decreases the flow into the chamber and decreasing pressure increases flow whereby fluid flow out from the chamber is maintained at a desired pressure. The outlet ...

A water pressure switch employs two pivotable plates and springs to control the activation of the pump. The arrangement of the two pivotably plates, the springs and the activation device reduces the space required so that a small box can accommodate all the parts.

An improved pressurizing sprayer removably attaches to the threaded neck of a container and includes a main body having a handle portion and a head portion. The handle includes a top portion with an exposed trigger and an inside portion in which a hand operated squeeze bulb pump is fitted. The head portion houses a pinch valve which is interconnected in-between a spray nozzle and a fluid conduit. Manually squeezing the pump delivers air into the container. Manually pressing the trigger continuou...

A pressure tank includes a liner separated into a cap and a main body. A shell covers the outer surface of the liner. The shell is formed of a fiber reinforced plastic. A heat exchanger is arranged in the liner. A header is connected to the heat exchanger. The heat exchanger is supported on the liner by fastening the header to the cap or the main body.

A pressure detector having a pipe inner pressure receiving opening section comprising a fluid passage for transporting fluid and a diaphragm hermetically sealing an opening made in one side face of the fluid passage, and a pressure detecting section coupled with the pipe inner pressure receiving opening section through the diaphragm and detecting physical variation of the diaphragm, characterized in that the diaphragm is provided loosely at the opening, and the pressure detecting section compris...

A transmitter configured to measure a process variable of an industrial process, includes a pressure sensor configured to couple to a pressure of a fluid. An acoustic detector receives an acoustic signal from the fluid. Measurement circuitry coupled to the pressure sensor and the acoustic detector provides an output related to pressure of the fluid.

An improved pressure reading structure for a pressure gage is disclosed, comprising a data plate, a rotable pointer and a protection casing. The data plate includes a central area and an extended area next to and connected to the central area, both of the areas being positioned on different planes to serve as an upper area and a lower area thereof respectively. In addition, the rotable pointer has a first end mounted above the central area of the data plate, a second end mounted above the extend...

A flexible pressure-washer hose and pressure washing apparatus are disclosed. The hose is of concentric laminar construction and comprises an inner core, an intermediate metallic sheath covering the core, and a jacket covering the intermediate sheath. The disclosed hose has a burst pressure of at least 12,000 psi, yet is highly flexible. The disclosed pressure washer comprises a hose made in accordance with the invention and fluidically connecting a source of pressurized fluid to an operator wan...

A gauge is provided for monitoring pressure of air or other gases within a tire or other gas containing chamber. A gauge includes a receiver attachable to a valve stem of the tire. A valve core is also provided on the gauge through which fill air can be directed. In this way, the gauge does not need to be removed during filling of the tire with air. A pathway extends from the valve core to the receiver within the gauge. A pressure sensor, such as a Bourdon tube, is coupled to this pathway and mo...

A pressure sensor having a diaphragm which is differently deformable or locally changeable by pressure differences is described. A construction advantageously usable even in poorly accessible spaces having high temperatures is obtained in that at least one functional section of the diaphragm has a material which has the properties of a black-body radiator or has an emissivity used for detection in the spectral radiation range corresponding to the temperature of the diaphragm under its conditions...
