What is a Proportioner?

A proportioner is a device that mixes two or more fluids together in a specific ratio, based on the pressure of the fluid being delivered. It is commonly used in hydraulic systems to control the amount of fluid being delivered to a particular component or system.

In a hydraulic system, the proportioner receives high-pressure fluid from a pump and delivers it to a low-pressure section of the system. As the fluid flows through the proportioner, it mixes with a second fluid, such as air or another liquid, to create a mixture that is proportional to the pressure of the fluid being delivered. This allows the system to maintain a consistent pressure throughout, even as the load on the system changes.

Proportioners are commonly used in applications such as hydraulic brake systems, where they help to regulate the amount of fluid being delivered to the brakes, and in industrial machinery, where they may be used to control the speed and torque of motors and other components. They can also be found in aviation systems, where they are used to regulate the pressure of hydraulic fluids in aircraft systems.

In summary, a proportioner is a device that mixes two or more fluids together in a specific ratio based on the pressure of the fluid being delivered, and it is commonly used in hydraulic systems to control the amount of fluid being delivered to a particular component or system.
