A fluid operated position regulator comprises a servo means, arranged in a
regulator housing and by which a supply connection, a venting connection
and a power connection can be placed in circuit in an adjustable manner.
To predetermine or set its position the servo means possesses two
mutually oppositely orientated fluid actuating faces of equal size, which
respectively delimit a control chamber. The two control chambers are
connected by way of an intermediately placed choke means with a common
control pressure connection. Downstream from the two choke means each
control chamber is connected with a venting connection. A control valve
means can control the two venting connections and in particular
simultaneously close them.
