• the wind motor 1 as shown in Fig. 2 and 3 functions as follows.
• transmission shaft 5 with rotor blades 41 will be rotated against the wind direction by guide blade 10 which tends to be parallel to the wind direction. Thus, all changes in the wind direction will be followed by the guide blade 10 and, followingly, by rotor blades 41.
• the rotation of transmission shaft 5 is transmitted by clutch 11 to compressor 2, which, in turn, pressurizes air led away through air conduit 13.
• control mechanism 42 At slow wind with small wind intensity, control mechanism 42 is in its initial position, the whole surface area of rotor blades 41 is impacted by the wind. Thus, this small wind intensity is enough to start the rotation of wind motor 1. But with increasing wind intensity, the centrifugal force borne in fly weights 50 will force them out of their initial position to move away from each other. In this way, the ring 43 will slide on the transmission shaft 5 by the lever mechanism of control mechanism 42 against the force of helical spring 48 towards holding piece 47. But sliding ring 43 takes with him connecting rod 52, too, which results in turning blade shaft 54 and, thus, rotor blade 41.
• the surface area of rotor blades 41 impacted by the wind will be smaller and, with this, the force borne on the blades 41 will be smaller, too.
• the transmission shaft 5 will rotate slower, more precisely, it will not rotate quicker when the wind intensity gets greater. Since the centrifugal force borne in the fly weights 50 is always proportional to the rotational speed of the transmission shaft, the movement of sliding ring 43 will always be proportional with the wind intensity. If the wind gets slower, the spring 48 forces sliding ring 43 towards its initial position and, thus, the rotor blades 41 will be rotated backwards.
• the direction of rotation of the transmission shaft 5 can be changed in a quite simple manner.

• the change-over cock 110 is operated in dependency of the pressure within water storage tank 26.
• a working valve 114 is provided the inside of which is divided into two compartments 115 and 116 by a membran plate 117.
• the pressure of water storage tank 26 (Fig. 1) is led through air conduit 25.
• a push rod 118 with head portion 119 pressed against membran plate 117 is slidably arranged.
• Push rod 118 is loaded in direction of membran plate 117 by a spring 120 which lies against a circular flange portion 121 of push rod 118.
• flange portion 121 cooperates with a bifurcated end 122 of a turning lever 123 pivoted at 124 and pivotally jointed at its other end 125 to an arm 126.
• the other end of arm 126 has a recess 127 cooperating with a pin 128 of a snap disk 129 pivoted at 130.
• the snap disk 129 is formed, at the same time, as a cam disk, on the periphery of which a cam 131 is provided, onto which a cam roll 132 is pressed by a spring 133.

• a chamber 140 is attached, near to the bottom of which, delivery pipe 29 has its entry in the inside of the chamber 140.
• the entry is formed as a valve 141 with weight valve body 142 which openes the entry only if the pressure is greater outside the delivery pipe 29 than in its inside.
• the chamber 140 has also a bottom entry formed as a valve 143 with weight valve body 144. In this case, too, valve 143 will be opened only if the pressure is greater outside the chamber 140 than in its inside.
• safety valve 16 built into air conduit 13 is shown in cross-section (Fig. 1). If the pressure within air conduit 13 will be to great, the force excerted on a ball 145 biased by a spring 146 will move away the ball 145 from an opening 147 and the pressure will escape through a blow-off opening 148. The pre-stress of spring 146 can be changed by an adjusting screw 149.
• device 12 for the air-tight connection between a rotating pipe and a stable pipe as used in air conduit 13 (Fig. 1) is shown in cross-section. It has two halfs 150 and 151 fixed together in an airtight manner. Between the halfs 150 and 151, a hollow shaft 152 with a flange 153 is arranged which can be freely moved in respect of the halfs 150 and 151. The other end of shaft 152 emerges from the half 151 and is sealed against it by sealing rings 154.
• the rotating portion of air conduit 13 is fixed to half 150, through the hollow inside of which the air is led to the hollow shaft 152 and further to the standing portion of air conduit 13 fixed to shaft 152.
• the sliding out of shaft 152 from the device 12 is prevented by flange 153 which lies against half 151.
• the water supply system as shown in Fig. 1 and 7 to 11 functions as follows.
• the wind energy converted by the wind motor 1 into rotational energy drives compressor 2 and the air pressurized by it is forwarded through air conduit 13 containing coupling device 12, non-return valve 15 and safety valve 16 to equalizing pressure tank 14.
• Non-return valve 15 prevents the backwards flow of the pressurized air towards compressor 2 and safety valve 16 limits the pressure within the system.
• the pressurized air gets from pressure tank 14 into change-over automaton 17 with the help of which water storage tank 26 will be charged with water coming from the well 21 or with pressurized air. This is important with an eye on the further delivery and use of the water supplied by this system.
• the pressurized air is forwarded by change-over automaton 17 from pressure tank 14 through air conduit 18 to pneumatic-mechanical control unit 19 and from there, through air conduit 22 to the producing head in well 21.
• the water will than be forced out of the well 21 through delivery pipe 29 into water storage tank 26.
• the control unit 19 returns into its initial position, thus, the pressurized air will not be forwarded into well 21 which, after this, can once again be filled with water in its natural way.
• the pressurized air will be collected in pressure tank 14 and, after reaching a given value of air pressure, the control unit 19 switches over for bailing water from the well 21 once again.
• the weight of float 36 and the measurements of tapered opening 38 are determined for leaving tapered upper portion 37 opening 38 even if there is a small overpressure within the tank 26, and, thus, the pressure exceeding that of the atmosphere can escape from tank 26 and will not hinder the filling up of tank 26 by the water .
• the pressurized air flows from change-over automaton 17 into air tank 81 of the pneumatic-mechanical control unit 19.
• the pressure increases until the force of spring 87 of operating valve 82 is not overcorned.
• This force can be varied by adjusting screw 92 according to the depth of the well 21. For example, if the well 21 has a depth of 20 meters, the pressure within air tank 81 can be adjusted to 2,5 bar. After reaching this value, the pressurized air will move away membran plate 86 from conduit 84 leaving free its opening and the air will flow into lower space 89 of operating valve 82 and, through air conduit 94, into lower space 93 of working valve 83. Membran plate 95 will be moved against the force of spring 97 together with valve shaft 98.
• working valve 83 will be enhanced by delay valve 104 the inside of which is connected through air conduit 108 to the lower space 93 of working valve 83.
• valve cup 106 closes pipe 105, thus, there will be no air loss in the upper end position of valve shaft 98 when air is fed into the producing head of well 21. If the pressure in lower space 93 of working valve 83 will be small enough to start the downwards motion of membran plate 95 and valve shaft 98, the air from lower space 93 will be forwarded through air conduit 108 into delay valve 104.
• the cross section of pipe 105 can be adjusted by screw 109, and the valve cup 106 can leave pipe 105 only under the retardation effect of spring 107.
• the pressurized air flows from compressor 2 through air conduit 13 into equalizing pressure tank 14, the volume of which is preferably two times greater than that of the chamber 140 of the producing head.
• the pressure in tank 14 starts to increase after closing the tapered opening 38 of float chamber 33.
• membran plate 117 will be moved against spring 120 of working valve 114. By the way, this predetermined pressure value can be adjusted by the force of this spring 120.
• Flange portion 121 of push rod 118 moved by membran plate 117 rotates turning lever 123 which pulls arm 126 rotating snap disk 129 by the cooperation of recess 120 and pin 128.
• Roll 132 moves on cam 131 of the periphery of snap disk 129, and lever 135 pulls arm 71.
• the cooperating slot 137 and nose 138 turn the valve body of cock 110 into its other position wherein the whole amount of pressurized air is forwarded from tank 14 through air conduit 111 and channels 112 and 113 and further through air conduit 24 into water storage tank 26, the inner air pressure of which can be observed by pressure gauge 28 (Fig. 1).
• the changing over of cock 110 has to be carried out in a quick manner. This can be solved by using snap spring 133.
• membran plate 117 of working valve 114 returns into its initial position, in the course of which the operation of change-over automaton 17 will be replied in an inverted sequence. After reaching the initial position, the water bailing from well 21 is once again possible.
