Single acting cylinder
single-acting cylinders have only one effective piston area. Single acting cylinders are mostly equipped with plunger pistons . However they can also be formed by the single sided application of pressure to a
Measurement uncertainty
DIN 1319). Figure M 16 shows these relationships based on the example of possible errors associated with a position measurement system.
Swash plate pump
in which the swash plate and the control disc are firmly connected to the drive shaft and rotate with it, while the cylinder block, which is firmly connected to the housing, does not rotate ( Figure T
Calculated pressure
are allowed to be operated. The calculated pressure corresponds to the rated value in accordance with DIN 40 200 (DIN 24 312).
Absolute pressure transducer
the side opposite the pressure to be measured is hermetically sealed as a reference chamber (e.g. with a glass plate or glass bushing). The reference pressure defined in this manner in the chamber can
Operating system
1. program in a digital computer system that together with the characteristics of the computer system forms the basis for the possible operating modes of the digital computer system and in particular controls
Phase shift
Refers to the shift, expressed as the angle φ, between two sinusoidal variables or signals with the same angular frequency ω such as the input and for a transfer element . The phase shift is described
Load-holding valve
In accordance with ISO 1219-1 load-holding valves are classed in the group of pressure control valves. They prevent double-acting consumers (such as hydraulic cylinders and hydraulic motors) that have
Three chamber valve
4/3 directional valve with three annular channels in the housing for the three ports A, B and P (Figure D 42) . The 4th port T is to the spring chambers F1 and F2 that are connected together via a connecting
Mechanical feedback
the moving part of the device to be controlled for the purpose of . Example: Two stage servo valve with flapper-nozzle system : here, a feedback spring (tube) is stretched while the valve control spool
