Screw-in throttle
Throttle valve that is designed as a screw-in cartridge.
Power input pump
The power input P of a pump is calculated from the pressure p and the flow Q as well as from the efficiency factor η of the pump. Alternatively, the power input can also be calculated from the torque
Oil heating
The heating ΔT of an oil volume V (without heat dissipation) is calculated from the supplied power PH, the period Δt of power supply, the specific heat capacity of the medium c (~1.88 kJ/(kg*K) for Oi
Short stroke cylinder
Cylinders whose stroke is significantly shorter than the piston diameter ( Figure K 41 ). Short stroke cylinders are used in hydraulics for things like tensioning or closing processes.
Pulse duration modulation (pulse width modulation)
Illustration of an analogue signal profile using the relative duration of a rectangular pulse within a specified cycle (period), which must become shorter as the process becomes more dynamic ( Figure
Sampling control circuit
Processes the discrete time signals from a sampler. It comprises a controlled subsystem with , a microprocessor, a sampler (mostly A/D converters) and a holding element (Figure A 9). The sampler sampl
