Natural frequency of a hydraulic cylinder
As a synchronizing cylinder (Figure K 5) with oil spring stiffness. The oil spring stiffness for cylinder side A and cylinder side B are arranged in parallel and add up to the total oil spring stiffne
Conical piston
Pump piston with a spherical piston area which uses the piston rings provided for sealing purposes. The piston shaft — unlike the spherical piston — is conical in shape and is responsible for taking t
Cavitation
Cavitation refers to the formation of cavities in fluids. Cavities start to from when the local static pressure within a fluid falls below a critical value. This critical value is generally about as h
Compact seal
Design category for seals with a block-like body and a less pronounced sealing edge. A characteristic feature is how the preload is applied not only by the sealing lips , but also by the body of the s
Combined actuation
According to DIN-ISO 1219, the combination of electrical and hydraulic actuation via a solenoid-actuated pilot valve ( electro-hydraulic actuation ).
Collapse pressure
Pressure at which a filter element becomes so crushed (destroyed) that it ceases to function. According to ISO 2941, however, the collapse pressure is simply the pressure at which the filter element i
Piston
The part of a hydraulic cylinder upon which the pressure of the medium acts and thereby generates a compressive force. F K = p 1 · A K — p 2 · A R Since friction occurs during the piston movement (par
Rodless cylinder
Cylinder design without a piston rod. As a result, these cylinders have an ideal short installation length just greater than the stroke. With the pistons not having any piston rod, both piston sides a
