Abstract (en)
An apparatus for keeping a fluid line circuit at a pressure by supplying fluid coming from a fluid reservoir, the apparatus comprising a pump device having an operating part and a pumping part, a fluid pipe putting the operating part of the pumping device in fluid communication with the line circuit, the operating element being arranged to make the operating stroke at an increase of the fluid pressure prevailing in the line circuit, the apparatus comprising a spring forcing the operating element into a position from which the operating element, at an increase of the fluid pressure in the line circuit, can made an operating stroke, the operating element and the pumping element having such dimensions that, at an increase of the fluid pressure in the line circuit, the force generated by the operating element is greater than an opposing force of the fluid on the pumping element, causing the operating element to make an operating stroke and the pumping element to make a pumping stroke. <IMAGE>
