How does the volume tank of an actuator work?

How does the volume tank of an actuator work?

The expansion process (while stroking) of the volume tank + volume of actuator can be considered as adiabatic process (a thermodynamic process in which no heat is transferred to or from the working fluid). The pressure regulator in the downstream of the volume tank will regulate the pressure at the actuator to its minimum required pressure.

How does a fuel filler door actuator work?

A fuel filler door actuator including a motor, a gear train coupled to the motor and to a latch arm, and a locking cam coupled to the gear train. The locking cam resists movement of the latch arm from an unlocked condition to a locked condition.

How is a volume tank similar to an accumulator?

The operating principle of this volume tank is similar with an accumulator on hydraulic actuator except it just a tank without any diaphragm or bladder to separate different fluid like in accumulator. The only fluid that fill the volume tank is the instrument air it self.

How does the pressure regulator in the volume tank work?

The pressure regulator in the downstream of the volume tank will regulate the pressure at the actuator to its minimum required pressure. It means, the final pressure of the volume tank after the actuator does a several strokes (usually 3 times stroke) shall be equal or greater than the pressure regulator set point.

How to replace fuel flap door lock actuator?

【REPLACEMENT FUEL FLAP DOOR LOCK ACTUATOR】Direct replacement for a proper fit and easy installation, meets or exceeds OEM standards. Just plug and play, no wire splicing necessary

Can a fuel tank be built as an open fuel system?

Before this change went into effect, fuel tanks were manufactured with a fuel filler cap that vented and released gas vapor into the atmosphere. To meet the new regulations, fuel tanks can no longer be built as an “open” fuel system.

How does the fuel tank ventilation valve work?

Gasoline expands in volume as it warms up and shrinks in volume as it cools down. The fuel level of your tank changes throughout the day, even if you are not driving it. You cannot put fuel into your tank, unless you can get the air out…and you cannot withdraw fuel from your tank unless you can let air in.

What makes a fuel tank meet EPA requirements?

Fuel demand valves prevent pressurized fuel from flooding your engine. New fuel tanks, designed to meet the EPA’s fuel vapor emissions standards, no longer have an open vent built-in to the filler cap. In addition, they are made from a material with high resistance to fuel permeation through the tank walls.
