Sales of the American Air-0Matic power-steering equipment in Britain are now being handled by Roger F. Fendley who has been appointed UK representative of the Sycon Corp. of Cleveland, Ohio, USA.
The Air-O-Matic unit has been produced in America for 20 years and is used by a number of major truck makers there. The equipment employs an air-pressure operated ram designed to be connected between a bracket on the chassis and a steering arm in a similar way to some hydraulicassistance systems. But advantages claimed over conventional hydraulic systems are the elimination of very-high-pressure hydraulic lines and a separate pump to supply the powersteering system. There are four basic models of Air-O-Matic available. These provide assistance from 1.250 to 2,800lb based on an air supply of 100 psi. with power-cylinder internal diameters of 4, Sand 6in. Each installation kit includes a safety valve which has the function of conserving air pressure for brake application if the pressure in the vehicle's air-reservoir falls below 55 psi. In this event the steering reverts to normal manual control as it does if there is a failure of the Air-O-Matic equipment, Made by Sycon Corp., Cleveland, Ohio. USA (UK representative Roger F.
