Valve
valves (lengthwise) and rotary valves ( Figure V 5 ), working method: specified switching positions (2-position directional valves, check valves, 3-position and multiple position directional valve), adjustable [...] position (manually operated directional valves), continuously adjustable valves ), controlled ports: 2-way, 3-way, 4-way valves and more; actuation (types): manual, mechanical, pressure (hydraulic, pneumatic)
Parallel circuit / connected in parallel
starts the movement ( Figure P 2 ). The next actuator only follows suit when the pressure at this point increases. Figure P 1: Resistances connected in parallel Figure P 2: Parallel circuit containing three
Sampling transfer elements
that measure and process the values for continuous variables at discrete times (E DIN 19 226, Part 2).
Tolerance of unit step response
the largest and smallest permissible deviations of the step response from the limit (DIN 19 226 Part 2).
Speed ratio
ratio of a hydrostatic transmission is defined by the ratio of the pump speed n 1 to the motor speed n 2:
Two-point controller
controller Non-continuous controller with two switching positions. The output signal can only take on 2 different values (neglecting the switching processes). Multi-position controller
Discontinuous controllers
output signal is discontinuous despite a continuous input signal (switching controller) Examples: 2-point or 3-point controller (DIN 19 225).
Pressure difference
Fluidlexikon Pressure difference Difference between two pressures p 1 and p 2 : If the pressure difference is the measured variable it is called the differential pressure p 1,2 (DIN 24 312).
Delay element
They are marked Tk, where the index k states the order of the delay (according to Din 19 226 Part 2).
