Symbolic representation of hydraulic aggregates and systems

Efficient transmission of energy from arbitrary types of primary sources and/or energy converters towaward appropriate control units and/or consumers can be a more or less complex process. In analogue to other existing branches of modern technology, energy transfer in agricultural machinery needs to be carried out very carefully, applying optimized technical solutions in each specified case. This factcts, (among many other problems) implies energy transmission that is technically, technologically, economically and environmentally aligned with the often difficult to predict dynamic needs of system components and the end user, with acceptable losses -at least in a wide range of possible environments defined by various possible conditions. This paper is the first upgrade of the series dedicated to the symbolic graphic representation of hydraulic system components according to valid technical standards. In this sense, the text presents and functionally describes only some of the much larger set of typical examples of hydraulic energy transmission and associated control functions in modern agricultural technology.
