Abstract: In a vehicle spring element with a connectable and disconnectable additional volume, it is on the one hand necessary for large volume flows to be exchangeable between the spring element and the additional volume via a connection and, on the other hand, it should be possible to open and close the connection with minimal auxiliary energy. A control valve (5) with a pilot device (67) is used for opening and closing the connection. Depending on the switching position of the pilot device (67) and with the aid of at least one movable partition wall (35), two closing elements (29, 30) can either free or close the path for the pressurised fluid through the control valve (5). The actuation of the pilot device (67) is accomplished with minimal auxiliary energy. By connection and disconnection of the additional volume to/from the spring element, it is possible to alter the spring rate (spring constant) of the spring element. The spring element is intended for springing between an axle and the body of a motor vehicle. <IMAGE>

Abstract: An exciter circuit for a gas turbine engine ignition system. A high voltage supply continuously charges a storage capacitor. A plurality of silicon controlled rectifiers (SCRs) are connected in series between the storage capacitor and a high voltage conditioning circuit. A multi-section protective network is connected in parallel with the series connected SCRs. Individual network sections are connected across separate ones of the SCRs. The SCRs are normally non-conducting and are periodically triggered to discharge the storage capacitor into the conditioning circuit. An igniter plug is connected to the output of the conditioning circuit. The protective network divides the voltage of the storage capacitor equally across the SCRs when the latter are non-conductive thereby reducing the voltage stress to which each of the SCRs is subjected.
