Rotary compressor: There is a rotary element inside the compressor casing that compresses the air.
R port: They are a special types of electronic ports that we use the connect different electronic devices.
Radial piston pump: The radial pistons are the main elements that we use to pressurize the air with radial piston pumps.
Ramped response: They are the response of a control system which has a graph like a ramp.
Risk assessment: In a different engineering projects and applications, assesment of possible risks and dangers of different parameters of the process. These activities are generally made with the people who are expertised in different fields. Everybody assess the possible dangers and precautions of that systems from every aspects.
Risk: Possible ratio of failure or possible ratio of danger of different systems and situations.
Reflex proximity sensor: The light beam is transmitted from the source to a retro-reflector that returns the light to the detector. When an object breaks a reflected beam, the object is detected.
Refrigerated dryer: They are the dryer systems that consenses the air by cooling the air. And this action takes the moisture from the air. They are very useful in lots of the pneumatic systems.
Regeneration: Regeneration systems in power generation or thermodynamical devices are the systems that uses the low quality remainder energy that in the exhaust or remainder fluids.
Relative humidity: Relative humidity is the ratio of the water vapor in a air-vapor mixture. RH is the acronym of this physical phenomenon.
Relief valve: Relief valves are the valves that we use the control the total pressure of the system. Once the pressure exceeds the required pressure, the relief valve opens to release the excess air in the room. They are very common systems in pneumatic systems.
Relieving pressure regulator: They are the pressure regulators that regulates the fluid pressure by escpaing air from the system or environment. So, pressure stays in intended value. They are very common in pneumatic systems.
Response time: In control systems, response time is the total time of response of the systems to the input signals or feedbacks signals.
Restriction check valve: They are the check valves that allows full fluid motion in one direction and restricted flow in other direction. The difference of them from othe types of valves, normal check valves does not allow any backflows unlike restriction check valves.
Return line filter: In hydraulic systems, they are the hydraulic fluid filters at the return line of the systems. When the hydarulic fluid returns to the reservior, they pass from return line filters.
Reynolds number: Reynolds number is a very common phenomenon that defined as the ratio of the inertia forces to viscous forces on a flowing fluids.
Rotary actuators: In hydraulic and pneumatic systems, they are the end effectors of systems that make rotary movement with the help of the high pressure fluids. We generally use them in clamping, positioning and transfeering of the different parts.
Rotary valve: They are type of valves in prevents any air loss on the rotary actuators of pneumatic systems.
Rotational speed: This is the general physical phenomenon in rotary systems. The general statement of rotational speed is rotation per minute or RPMs.
RTD sensor: They are the types of sensors that converts the temperature value to the equivalnet proportional signals. They are very common in heat applications such as ovens.
Running torque: The torque value to keep one part rotating against another.
Regulating valves: Valves that regulates the enterance of fluids or liquids in pneumatic and hydraulic systems.
