Magnetic filter
Filter with a permanent magnetic element for retaining ferromagnetic particles. Magnetic filters are often combined with fleece or screen filters and thereby increase the amount of contamination they
Half open hydraulic circuit
If the principle of the closed circuit is applied to a differential cylinder , the fact that different areas are involved means suction must also take place from the container when switching to feed m
Valve polarity
Ratio between the direction of the controlled hydraulic fluid flow and the direction of the electrical input flow for continuously adjustable valves.
Transfer element
In general : A system with input variables u 1 (t ) ... u p (t ) and output variables v 1 (t ) ... v q (t ), which has a certain transfer function , is called a transfer element (EDIN 19 226 Part 2) (
Blowing past piston seals
On the piston seal of a double acting hydraulic cylinder, in the case of a poorly designed piston seal, pressure fluid can flow from one side of the piston to another in a short time, normally if very
Symbols
Abstract illustration in the form of graphical symbols, which display the function of a fluid device (not its construction design) in accordance with a standard or a key. The symbols were previously k
Flow switch
Devices, which contains an electrical switch, the contact of which is actuated at a given flow of the hydraulic fluid.
Control command
The signal, which brings about a state change as the result of a signal formation or signal processing.
Plug-in board
Circuit board , which contains a multiple plug, which groups all outward-leading connections of the various functions.
