(11) The containment tank 6 has a first tank portion 6a connected to the intake or supply duct 4 and a second tank portion 6b connected to the transfer or discharge duct 5.

(12) A compensation valve 8 is interposed between the first tank portion 6a and the second tank portion 6b.

(13) The rotor 3 comprises a three-lobed structure which forms three side walls 31, 32, 33 which cooperate with the stator chamber 2 in order to form, during its rotation about the axis 100, an intake chamber 41 at the outlet 4a of the first intake or supply duct 4, a discharge chamber 42 at the outlet 5a of the second transfer or discharge duct 5, and a compression chamber 43.

(14) In particular, the rotor 3 has a blade-like portion 60 which forms a counterweight.

(15) Preferably, the containment tank 6 has an oxyhydrogen refilling port.

(16) Conveniently, the rotor 3 comprises bronze or Teflon contact shims 3a.

(17) In fact, since no combustion occurs inside the stator, there is no risk due to overheating of the contact shims 3a.

(18) According to a first embodiment shown in FIGS. 1 to 4, the axis 100 of the rotor is fixed.

(19) In this case, the contact shims 3a can move in a radial direction with respect to the rotor axis 100.

(25) In this embodiment, the stator chamber 2 and the rotor 3 have a shape that is similar to the shape of a stator chamber and of the respective rotor of a Wankel engine, and the relative movements are substantially similar.

(26) However, there is no combustion as in the classic Wankel engines but rotation is determined by the expansion of the oxyhydrogen in the intake chamber 41, while the discharge is ensured by the inertia of the blade-like portion provided with the counterweight 60.

(27) According to a preferred embodiment shown in the figures, the movement device 1 comprises a timepiece 10.

(28) As shown in the figures, the timepiece 10 has a case 11 which accommodates the stator chamber 2.

(31) The pressure can vary according to the characteristics of use, such as the rotation rate and the run time.

(33) The pressurized oxyhydrogen is loaded into the containment tank 6.

(34) The passage ports of the first intake or supply duct 4 and of the second transfer or discharge duct 5, as well as the compensation valve 8, are sized in order to ensure the rotation of the rotor 3 inside the stator chamber 2 at a certain angular velocity and for a preset time which depends on the operating pressure, on the quantity of oxyhydrogen contained in the containment tank, and on the overall frictions.
