Water supply system, energy conversion system and their combination

In apparatus for supplying water from a source of water, a producing head arranged within the source of water and operated by compressed air, and a compressor driven by a wind motor for compressing air for the producing head;

• the improvement comprising means for the temporary storage of water from said source of water, and means responsive to the level of water in said temporary storage means selectively to supply said compressed air to said producing head so as to maintain a predetermined water level in said temporary storage means, a pressure tank to which said compressed air is supplied, a changeover device responsive to low water level in said temporary storage means to direct air from said pressure tank to a control unit and thence to said producing head, in which said control unit (19) has an air tank (18) connectible to the pressure tank (14) through the action of said changeover device, a working valve (83) for connecting the producing head to the air tank (81) or to the atmosphere, and an operating valve (82) between the air tank (81) and the working valve (83) for operating the working valve (83) depending on the pressure in the air tank (81), and a membrane (95, 86) in each of the working valve (83) and the operating valve (82) separating inner spaces of said valves into two compartments (88, 89;
• 96, 93), in the first compartments (96, 88) of both valves (83, 82) the membranes (95, 86) are each urged by a resilient means and the second compartment (89) of the operating valve (82) is connected through an air conduit (84) to the air tank (81), the air conduit (84) is opened or closed by the membrane (86), and the second compartment (89) of the operating valve (82) is connected to the second compartment (93) of the working valve (83), and the working valve (83) has a valve shaft (98) moving with the membrane (95) within a channel (100) of the valve housing, and the valve shaft (98) has a through bore (102) for establishing connection between the air tank (81) and the producing head or between the producing head and the atmosphere, respectively.
