Braking valve
Pressure valve that prevents a pulling load adopting an uncontrolled velocity. This problem occurs if the work equipment can run away from the inlet oil flow. To prevent this situation arising pressur
Pre-charge of seals
Contact pressure of elastomer seals on the surfaces to be sealed, which arises when the seal is installed . To that end either –– as in lip seals — the lips are designed to be undersized or oversized,
Correcting range
Range within which the correcting variable can be adjusted (DIN 19 226).
Friction losses
The energy irreversibly converted due to the friction, which is removed from the system in the form of heat. In fluid technology, these losses occur due to friction as a result of the viscosity of the
Measuring amplifier
Device which amplifies the mostly very weak during electrical measuring procedures (e.g. 2 mV/V bridge voltage for strain gauges) to a level required for the purposes of display or further processing.
Hydraulic motor
Device for converting hydraulic energy (Q, p) into mechanical energy (M, n) by creating a certain torque and rotation speed. Neither is dependent on the other: the rotation speed n 2 is only dependent
Valve efficiency
The efficiency of a valve is determined by the pressure losses and the leakage losses . In most cases, the pressure losses Δp dr, which are comprised of form-related losses (form drag ratio) and throt
Intrinsically safe
1. Term from electrical engineering: An intrinsically safe device has a power level so low that it can be used in potentially explosive atmospheres. 2. Machine controls are intrinsically safe if, in t
