2021年5月21日 · 3/2 way valves are generally used to control single-acting actuators. It can be normally open or closed. 4/2, 4/3, 5/2, 5/3 way valves are normally used for double-acting actuators. Example: Find below a hydraulic circuit that describes how a directional control valve works. In a 4/2 directional control valve, 4 ports, 2 positions.

DCV is used to control a single-acting cylinder. Figure 1.12(a) shows the valve in its normal position in which the pressure port i. blocked and the outlet is returned to the tank. This allows the force of t. e to act on the piston and retract the cylinder. The cylinder remains in the retracted p.

3*2 DCV is used instead of carburetor. Special Pneumatic pipes are used for air flow. Figure 5 Modified Brayton cycle. Analysing the engine we found that the engine works on a modified Brayton Cycle, modified in the sense that the exhaust of the engine is not at the same pressure as that of the intake of the compressor.

Table 1 shows the Port markings of DCVs. The cross sectional views of 3/2 DCV (normally closed) based on spool design is shown below. When the valve is not actuated, port 2 and 3 are connected and port 1 is blocked. When the valve is actuated then port 2 and 1 are connected and port 3 is blocked.

The pneumatic pipes are used to connect the air reservoir to the engine cylinder . Cam mechanism used in the IC engine of luna is replaced by custom made cam for required valve timing. 3*2 DCV is used instead of carburetor. Special Pneumatic pipes are used for air flow.

A 3/2 Directional Control Valve (DCV) is a crucial component in fluid control systems, typically used in pneumatic and hydraulic applications to manage the direction of airflow. The “3” in 3/2 refers to the three ports of the valve: inlet, outlet, and exhaust.

Figure 1.2 shows the construction of a disc type 3/2 way DCV. When push button is released, ports 1 and 3 are connected via hollow pushbutton stem. If the push button is pressed, port 3 is first blocked by the moving valve stem and then valve disc is pushed down so as to open the valve thus connecting port 1 and 3.
