Abstract:
1. A fluid power arrangement comprising a valve means and a fluid power implement, which is connected or is able to be connected with the valve means by way of a first fluid line and at least one second fluid line for fluid actuation through the valve means, the valve means and the implement constituting spatially separate assembly units, the valve means having a first valve fluid port for the first fluid line and at least one second valve fluid port for the at least one second fluid line and the implement having a first implement fluid port for the first fluid line and at least one second implement fluid port for the at least one second fluid line, wherein, on the first valve fluid port and the first implement fluid port on the one hand and on the at least one second valve fluid port and the at least one second implement fluid port on the other hand, mutually different port encodings are provided so that a coordination of the first valve fluid port with the first implement fluid port and of the at least one second valve fluid port with the at least one second implement fluid port is apparent on the basis of the respective mutually corresponding port encodings, and wherein fluid line encodings are provided on the first or on the at least one second fluid line at least at the their terminal portion associated with the implement fluid ports or the valve fluid ports, the fluid line encodings corresponding to the port encodings, and wherein the port encodings and/or the fluid line encodings include colored encodings, and wherein at least one colored encoding is provided on a colored marking ring, such ring being arranged or being able to be arranged on the respective fluid port or the respective fluid line, and wherein the colored marking ring is adapted to be detachably secured to the respective fluid port or the respective fluid line, and wherein the port encodings and/or the fluid line encodings include mechanical markings, and wherein the mechanical markings are haptically distinct so that they may be sensed by the user.
