description

In addition to turbines, motors based on the expansion principle, e.g. piston motors, screw motors, are used to generate mechanical energy from steam. Due to the technically achievable temperatures of below 100 ^° C. through solar energy, the use of easily evaporable refrigerants such as Freon is of particular importance. Due to its extremely low viscosity and high volatility, the medium freon makes special demands on the internal and external tightness of the engine. The engines currently being developed specifically for this medium are piston engines with v / end valve control and output; they are complex and expensive in terms of production technology, and also heavy.

The motor proposed here works on the principle of the vane motor, in which the steam in variable-volume, dense cells can release their energy to the rotor by relaxing, see FIGS. 1 to 4. This motor is characterized by special advantages:

- simple construction and thus simple production and maintenance

- No moving parts apart from the rotor

- smooth rotation

- lightweight construction

- Robustness

The engine can be used, for example, in sunny areas to drive water pumps for irrigation.

The internal tightness of the engine can be improved by developing Loosen suitable sealing lips on the blades and on the rotor. The tightness to the outside takes place through measures, as used in refrigerant compressors, and thus corresponds to the state of the art.

A special design with regard to hermetically sealed construction is shown in FIG. 4, in which there is a magnet armature in the motor is integrated so that the output can take place by induction like an electric motor.

Description continued

Fig. 1 shows a radial section through the steam engine, in which the axis oo of the rotor (7) is mounted eccentrically to the housing axis II. The rotor is set in rotation by the gas pressure acting on the blades (. Pressurized steam can relax as it rotates through the volumetric cells and thus transfer its energy to the rotor.

The wings (3) are flexible and adapt to the Housing Geonu'trie; they are embedded in the rotor and firmly connected to it. The sealing lips (7) seal the cell radially and laterally by resting on the housing. A special sealing bead (4), which is connected to the blades and the motor, seals through axial contact with the housing the cell radially inwards.

Fig. 2 shows an axial section of the steam engine in Fig. 1.

The output takes place via the output shaft (8), which is sealed from the outside by means of a stuffing box (6).

Fig. 3 shows an alternative proposal for the attachment the wings (10), which are rotatably mounted in a bearing point (11) and are also flexible. This arrangement serves the reduction of the bending stress on the wings consists of an axial bore in the rotor (12) with a milling so that the so-formed wing is pushed in can be rotated over an angular range, but is fixed radially.

The bearing bore has an 'embedded' in an axial groove Seal (13) for sealing the cells against one another. The sealing bead (14) connects to the lateral seal of the wings (10) in the bearing point (11); it is embedded in the rotor and its axial contact with the housing causes the cell to be radially sealed towards the inside.

Fig. 4 shows an axial section through the steam engine in Fig. 3. The picture shows the arrangement of the blade (10) in the rotor (12), as well as the arrangement of the seal (13) and of the sealing bead (14).

The functional principle differs from FIG. 2 by the integration of a magnet armature in the motor housing (1), whereby the output to the outside is possible according to the electromotive principle ; the engine can thus be built completely tight .
