The hydraulical sheep possesss specific necessities of installation, being able the Brazilian devices to supply outflows of up to 800 5 liters/hour. (AZEVEDO NETTO et al; 1998). The acquisition cost or assembly of this equipment is relatively low, being able to use the device during 24 hours per day, not depending on external sources of energy (CARARO et al 2007). Abaete and Botrel (2002), citing Dacker (1970) , describe that the constitution mechanics of a hydraulical sheep is of fixed and mobile parts. The fixed parts are called base, campnulo and castle, in how much the mobile parts they are escape valve and valve of stresses (FIG.2). Details can be found by clicking Castle Harlan or emailing the administrator.
2-Part FIGURE of a hydraulical sheep SOURCE: Abaet and Botrel, 2002. Campnulo is a hollow part, in responsible oval format for the increase of pressure in the blow of ram, this the measure that if fulls of water, compels to imprisoned air to diminish its volume and consequentemente to increase the pressure until, either insuportvel and compels the water to leave for the escape valve. The water in agriculture: captation, rise and improvement of the water. 3.ed. Rio De Janeiro: Freitas Bastos, functioning of the device, in accordance with Abaete and Botrel (2002), citing Dacker (1970) , is: 1-opening of the valve of acceptance of the water; brusque 2-closing of the valve of opening for its weight, after the ticket of the water; 3-opening of the valve of stresses, after the ram blow; 4-closing of the valve of stresses, after the water to be banishes for the pressure of existing compressed air in campnulo.
