The Compressed Air Reservoir or Storage Tank(see Figure 2.1.4)
Hold this component in your hands as you read the following description.
Reservoir Specifications
Reservoir Bore is approximately 1-1/2 inches or 38mm
Interior Cylinder Length is approximately 5-1/4 inches or 133mm
Recommended Operating Pressure for the reservoir is 150 psi. Do not exceed this operating pressure or the regulator will be damaged
The bicycle pump transforms work into the (Potential) energy of pressurized air. This pressurized air is stored in the reservoir. The potential energy captured or stored in the reservoir comes from the energy (Work) you expended pumping the air into the cylinder. In other words, some of the work of pumping the air is now stored and ready for use within the reservoir.
The reservoir is comprised of a Stainless Steel tube with 2 aluminum end caps. The end caps are identical, and each has a 1/4 inch NPT, National Pipe Thread, threaded port and threaded mounting bosses.
A Schrader valve is threaded into one end of the reservoir. The end of the bicycle pump hose locks onto the Schrader valve during filling. The locking feature allows a single person to fill the reservoir.
A One Touch, quick connect fitting is threaded into the other 1/8 inch NPT (National Pipe thread) port. These fittings provide an easy means of quickly assembling and disassembling pneumatic circuit components by allowing hoses and tubes to be easily and quickly disconnected and reconnected.
3 Way Shut Off Valve
Hold this component in your hands as you read the following description.
The 3 way shut off valve is referred to as a 3/2 manual valve. (see Figure 2.1.5)
The 3 way shut off valve is connected between the pneumatic reservoir and the regulator.(see Figure 2.1.14) This hand operated valve has 3 ports and 2 states or operating positions.
3 Ports
The P port is connected to the pressurized air supply or reservoir. (see Figure 2.1.15)
The A port is connected to the circuit and supplies the circuit with pressurized air when the valve is turned on.
The E or exhaust port vents the circuit when the vale is closed, and serves to depressurize or de-energize the circuit.
Off Position:
In this position the valve handle is perpendicular to the flow of air through the valve. As the valve handle is turned to the off position the valve will vent the circuit pressure.
On Position:
In this position the valve handle is parallel to the flow of air through the valve.
Venting the circuit during shut down is a pneumatic safety feature. Venting or depressurizing the pneumatic circuit and components prevents the possibility of inadvertent operation of the system or any system components.
Note: The 3 Way Valve is a directional valve. Be certain to align the flow of air through
the valve with respect to the directional arrows embossed on the valve housing. Connecting the valve in reverse will vent the reservoir when the valve is turned on. (see Figure 2.1.16)
