A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa), [2] [3] petrol pumps (in Commonwealth countries), or gas pumps (in North America).
The purpose of Vuilleumier's machine was to create a heat pump that would use heat at high temperature as energy input. The Vuilleumier cycle... utilize[s] working gas expansion and compression at three variable volume spaces in order to pump heat from a low to a moderate temperature level. The interesting characteristic of the Vuilleumier ...
Drawing of a centrifugal "fly-ball" governor. The balls swing out as speed increases, which closes the valve, until a balance is achieved between demand and the proportional gain of the linkage and valve.
Two-gauge pressure regulator connected to gas cylinder used for breathing gas supply. Pressure regulators are used with diving cylinders for Scuba diving. The tank may contain pressures in excess of 3,000 pounds per square inch (210 bar), which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled ...

Piston pump compared to a plunger pump. A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. [1] Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate.
The vector sum of V R and the voltage drops equals V S, and it is apparent in the diagrams that V S does not equal V R in magnitude or phase angle. Voltage phasor diagrams for a short transmission line serving lagging, in-phase, and leading loads. The diagrams show that the phase angle of current in the line affects voltage regulation ...
A voltage-regulator tube (VR tube) is an electronic component used as a shunt regulator to hold a voltage constant at a predetermined level. Physically, these devices resemble vacuum tubes, but there are two main differences: Their glass envelopes are filled with a gas mixture, and
