Response time of a cylinder
Time that is measured between the hydraulic fluid entering the cylinder and the start of the piston movement.
Return line pressure
Pressure created by flow resistances which must be overcome when feeding back the pressure fluid (to the tank).
Absolute pressure gauge
Device that indicates the absolute pressure at a measuring point in a hydraulic fluid, referred to a perfect vacuum.
Suction line
connected to the intake port of a hydraulic pump or compressor and permits the transport of hydraulic fluid.
Flow switch
contains an electrical switch, the contact of which is actuated at a given flow of the hydraulic fluid.
Usable volume
The proportion of hydraulic fluid within the total volume of a hydraulic accumulator that can be removed without causing any damage.
Separator
Device for separating small particles of dirt from the hydraulic fluid based on other particle characteristics apart from the particle size.
Viscosity range
Range within which the viscosity of a hydraulic fluid satisfies the requirements placed on it. It is defined by operating conditions.
Hydraulic power pack
accordance with the size of the consumers and thus the overall need for fluid in the hydraulic system. The warming of the fluid, as well as potential leakages must be taken into consideration here. The [...] hydraulic power pack is a stand-alone assembly consisting of a drive motor, hydraulic pump and hydraulic fluid tank. The drive motor is connected to the hydraulic pump via a shaft and drives this. The motor and
Radial piston pump
perpendicular to the drive axis. They can be subjected to pressure from the inside or outside by pressure fluid and are, amongst other things, suitable for high constant pressures . Pressurised from the inside [...] The pistons in the fixed cylinder block are moved by an eccenter on the drive shaft. The hydraulic fluid flow is generally controlled by suction and pressure control valves ( Figure R 5 ). Another concept
