Gap filter
Filter consisting of a set of fine metal discs with a defined distance and which also determines the maximum filtration grade (Figure M 23). The gap filter is one of the surface filters , i.e. it has
Hydraulic cylinder
Cylinder designed to be used with hydraulic fluids at generally higher pressures (of around 100 bar and above). Given the relatively low compressibility of the fluid and the low weight of a piston, hy
Four quadrant operation
Operating modes of drives
Switching methods for hydraulic pumps
Considerations on switching methods for hydraulic pumps are necessary if several pumps are used in a hydraulic system . A distinction is then made between ( Figure S 17 ): two-circuit or multi-circuit
Pressure regulator (zero-stroke regulator)
Fixture which changes the flow rate of a variable pump in such a way that is becomes ever smaller as the pressure increases (e.g. up to around 5% of Q max). The pressure at which adjustment starts is
Hydrostatic traction drive
Hydrostatic transmission for a stepless vehicle drive which generally operates in a closed circuit with primary control (pump control) or primary and secondary control (pump and motor control). If a s
Limit switch
On reaching a set pressure these switches actuate a normally open or normally closed contact. Limit switches are predominantly installed in pressure gauges ( Contact pressure gauge ). A differentiatio
Modular system
System comprising several parts, normally a basic part and any number of additional parts from which functional elements of a varying nature, e.g. cylinders or valves and also machines can be assemble
Set geometric displacement
Displacement volume of a hydrostatic pump or displacement volume of a hydrostatic motor.
