摘要: A resonant cavity of a microwave generator, such as a magnetron oscillator, is provided with a tuning piston which is displaceable between two terminal positions, corresponding to respective limiting frequencies f.sub.1 and f.sub.2, by means of a rotating crankshaft to which the piston is coupled by a linkage including a pitman with a substantially linearly guided extremity remote from the crankshaft axis. The length p of the pitman, measured between the pivotal axes of its extremities, is related to the eccentricity e of the crankshaft by the expression ##EQU1## where q is the length of the stroke of the linearly guided extremity between its extended dead-center position and an intermediate position in which the operating frequency of the generator has its mean value (f.sub.1 +f.sub.2)/2. With this dimensioning, the frequency varies as a sinusoidal function of the crankshaft angle and is therefore proportional to the output voltage of an angle sensor coupled with the crankshaft.

摘要: A magnetron with a central cathode coaxially surrounded by an annular anode forming an array of cylindrical resonant cavities is tunable by an axially movable disk carrying hollow plungers which project into these cylinders, the disk being spacedly overlain by a lid or wall member defining therewith a shallow chamber for the circulation of a cooling fluid. The fluid enters and leaves via expandable inlet and outlet channels to traverse not only the chamber but also the interior of the several plungers. The axial adjustment of the disk is brought about by rotation of a ring with an internally threaded hub engaging a complementarily threaded hollow boss rigid with the disk, the chamber communicating with the interior of the boss through peripheral apertures of the latter. The fluid is branched off a hydraulic circuit for the cooling of the stationary electrode structure formed by the anode and the cathode.
