power valve

The biggest engine downfall was the lack of a power valve.

This produces little power and so the system must use a low power valve to control the gas.

However as power valves are in the hot gas flow they need regular maintenance to perform well.

During the 1960s to early 1970s, distortion was primarily created by overdriving the power valves.

The vehicles' power valve screws in the intake manifold may come loose.

Many modern two-stroke engines employ a power valve system.

Many power valves have good linearity but modest gain or transconductance.

Power valves are capable of high frequency response, up to at least 30 MHz.

Most vehicles need only the power valve screws replaced, but some could require more extensive repairs, including a new engine.

This is usually addressed with a spring-loaded "power valve", which is held shut by engine vacuum.

The output transformer sits between the power valves and the speaker, serving to match impedance.

The power valve is controlled by an ECU and servo motor.

The twin-barrel Hitachi carburettor was significantly improved with the addition of a power valve circuit.

Two-stroke engines use a power valve system to get similar results to VVT.

The first few production units almost copied the Bassman circuit, with American military surplus 5881 power valves, a relative of the 6L6.

Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s.

The Power Valve is a series of four plates in the QR25DE 4-cylinder engine, one per cylinder.

Power valve actuation can be by mechanical (RPM dependent) or electric (servo motor) means increasingly with electronic control.

The most recent problem was an attempt to restart a compressed-air system that is used to power valves that control the flow of cooling water in the plant.
