Claims

2 is paired with the lever 3 via a spring-loaded roller 5 and a frequency tuning unit, made in the form of a ster, mounted 6 with a lead screw 7 and a tuning knob 8, which is mounted on its end with the possibility of longitudinal movement, the rod 6 having a roller 9, the axis of rotation 10 of which lies on a straight line with the center of axis 4 of rotation of lever 3 and axis 11 of roller 5 on rod 2, moreover, the total thermal expansion of the structure between the center of axis 4 of rotation of lever 3 and the end of a thermostable resonator is equal to the total thermal expansion of piston 1 and rod 2, the coefficient of total Teiuiv Boro expansion of the frequency tuning node is equal to the sum of the coefficients of thermal expansion of the structure between the axis 4 of the rotation of the lever 3 and the axis of the rod 6. The thermally stable resonator works as follows. The mixing of the piston 1 is carried out parallel to the longitudinal axis of the cavity 13 of the thermostable resonator. In this case, the roller 9 rolls along the lever 3. At the same time, the roller 5 also rolls along the lever 3. The rod 6 with the roller 9 moves in the direction specified by the sleeve 14 and provided with a threaded coupling 15. The rotation of the coupling 15, as well as the adjustment knob 8 attached to it and the scales 16 are directly proportional to the displacement of the rod 6 and to the change in the resonant frequency of the thermostable resonance determined by the displacement of the piston 1-. The scale 16 has a frequency scale with frequency diagram. The proportionality factor is determined by the ratio of the cavity length 13 and the resonance wavelength, the speed of light, the lead screw thread pitch 7, the arc length of the scales 16, and the product of the distances from the axis 4 of the rotation of the lever 3 to the axes 10 and 11 of the rotation of the rollers 9 and 5, respectively. Adjustment of these distances is carried out by moving the axis 4 of rotation of the lever 3 with the holder 17 in the holder 18. The length of the rod 2 is controlled by moving its rod 19 in the holder 20 in the direction of the longitudinal axis of the cavity 13. The relative position of the axis 10 of rotation is adjusted by rotation of the scale 16 relative to the coupling 15 roller 9 and scale 16. With the HELP of the above-mentioned adjustments, an accurate setting of the resonant frequency over the entire tuning range is achieved. In addition to this, a linear relationship is achieved between the resonance frequency and the position of the rod and the scale 16. The loop 21 of the connection serves to input and output signals from a thermostable resonator.
