modular construction of a pneumatic process-control system

Disclosed are a pneumatic control method and device.

Integrated as part of the pneumatic control system is a pneumatic system that includes a reservoir (64) recharged during the deflation cycle.

A player controls the vertical position of the prize by means of a pneumatic control valve.

Advantages of a pneumatic control valve with a position regulator of this type are lower air consumption and wear and greater regulating accuracy.

An improved pneumatic control system inflates and deflates an inflatable CPR vest (10) in a controlled manner.

An air-regulated ballast block (8) is secured to the bottom ring (6).

The air-regulated ballast block (8) is designed like a tank provided with an opening (9) for air and with water intakes (11).

The invention relates to a controllable ribbed thermoinsulative chamber of continually adjustable thickness, which is used to pneumatically determine its thermal conductivity.

When the maximum load is required, the pneumatic component control valve is fully open and can not handle this condition.

A pneumatically regulated movement cushion for deep relaxation, having a plurality of independent chambers and, in each case, a single supply hose for each chamber, it being possible to fill and empty the respective chamber via the supply hose.

A low pressure pneumatic valve control system having at least one manually actuable pilot valve (1, 2) to control a respective remote slave valve (3, 4).

For dispensing lubricant, at least one lubricant dispensing port and at least one ventilation port can be opened in a pneumatically controlled manner on the small volume lubricant dispenser.
