Position diagram
Reflects the workflow of a drive element (e.g. rapid movement –– feed –– reflux of a feed cylinder). It consists of functional lines for individual movements in connection with drive and signal elemen
Pressure switches
Devices that close or open electrical contacts in the event of pressure load (DIN ISO 1219-1). They are generally used if an electrical switching command or status signal should be issued when a set (
Laminar flow resistor
Flow resistor () with laminar flow, e.g. capillary gap. Has a largely linear flow rate pressure characteristic .
Control block (valve block)
Metal block, which houses several valves through incorporation or addition. The connections necessary for it to function are drilled into the block and are connected to the corresponding lines.
Valve control with four edges
Hydraulic resistance control for an actuator with two type A hydraulic half bridges. For example, the control of a hydraulic cylinder with a dual effect with a continuously adjustable directional valv
Shear stability of a hydraulic fluid
Resistance of a liquid to changes in viscosity under shear stress (CETOP RP 100).
Operating parameters
Factors (boundary conditions) that affect the operational sequence and the function of systems and devices. These include the load curve, behaviour, installation conditions, operating conditions etc.
Incremental digital measuring system
Counting-only measuring system in which first a reference point must be moved to such that a specific position can be determined by counting increments forward or backward (Figure D 29) . The position
Sealing lip
That part of a lip seal that generates the preload during installation (Figure D 13) . On compact seals the sealing lip is often shortened to form a sealing edge.
