Air/Hydraulic Actuator

High Performance, Versatile

MICO Air/Hydraulic Actuators combine a large surface area air chamber with a smaller diameter bore master cylinder or actuator. MICO's versatile, high-performance air/hydraulic actuators are designed to take advantage of available pressurized air sources to product high hydraulic pressure. They can be used on a variety of vehicles and industrial applications within the construction, material handling, mining, forestry, and agriculture markets.

Unique application: A towed vehicle that is hydraulically braked and equipped with an air/hydraulic actuator can utilize the air-actuated brakes of the vehicle that is towning it.

 

Air/Hydraulic Actuator
Master Cylinders with Air Chamber

MICO Master Cylinder type air/hydraulic actuator is the combination of conventional master cylinder and an air chamber. The master cylinder is single acting type with one piston.

Air pressure is used to actuate a push rod in the air chamber. The push rod in turn moves the piston in the master cylinder which forces the hydraulic fluid into the system.

 

Available with or without internal residual check valve

Incorporates a conventional master cylinder

Sealed diaphragm fluid reservoir

Available for industrial and mobile applications

Air/Hydraulic Actuator
Straight Bore Master Cylinder with Air Chamber

This air/hydraulic actuator is similar to those found above. This model however, uses a larger straight bore master cylinder for more displacement and a larger air chamber for more pressure. Like the previous model, air pressure is used to actuate a push rod in the air chamber. In turn, the push rod moves the master cylinder piston which forces hydraulic fluid into the system.

Air/Hydraulic Actuator
Stem Seal Master Cylinder with Air Chamber

These air/hydraulic actuators are a combination of a fluid actuator and an air chamber. MICO designed them to take advantage of available pressurized air sources to produce hydraulic pressure. The stem seal actuator eliminates cup cutting by allowing the cups to move freely in the master cylinder without passing over any ports.

 

Includes stroke indicator

Available for industrial and mobile applications using hydraulic oil or brake fluid

Internal valving design enhances bleeding process and extends normal service life of primary seal

Air/Hydraulic Actuator
Stem Seal Actuator with Air Chamber

MICO's straight bore actuator type air/hydraulic actuator is the combination of a remote actuator and an air chamber. The remote actuator has single acting piston with a stem seal. The stem seal actuator eliminates cup cutting by allowing the cups to move freely in the master cylinder without passing over any ports.

 

Allows towed vehicle's brakes to be controlled from brake pedal of towing vehicle

Ideal for spring brakes - cup seals never pass over ports

Available for industrial and mobile applications
