areas to be sealed, the shape and hardness of the seal and the durability of the medium. The film of fluid on the wall associated with the escape lifts the sealing lip and therefore remains on the surface

actuator in the form of discontinuous movement. In addition, it causes in the pump and in the hydraulic fluid a pressure pulsation.

Vessel for collecting and to some extent conditioning hydraulic fluid (removal of contamination and air, quietening). Is used at the same time to remove dissipated heat , however it is only suitable for

hydraulic energy is in general produced by hydraulic pumps, the conducting section, comprising and fluid power control devices (control elements) and the motor section in which the hydraulic energy is converted

= 1.2*v m . As of a certain flow speed, which depends on the pipe diameter and the viscosity, the fluid becomes heavily swirled (turbulent) and this results in a high energy loss. This flow should generally [...] depends on the Reynolds number . As the formation of a laminar flow requires a build-up distance of the fluid flow pattern l a = 0.03 d i · R e (for example 20 mm internal pipe diameter approx. 1.3 m) compared

Since actual fluids are compressible, they behave like a spring when pressure is applied to them: the higher the pressure, the more they are compressed and the smaller their volume becomes. The spring

series circuit) of several subsystems: For example, one subsystem is the plant to be influenced, in fluid technology this is often a cylinder with a connected load, the second subsystem is the immediately

gear wheels with teeth on the outside that rotate engaged in each other. As a result the hydraulic fluid is pressed out of the gaps between the teeth on the outlet side, while the necessary vacuum is produced

accommodated based on the pressure increase required. It is a function of the compressibility of the fluid. The compressibility of the oil in a pipe is increased by the elasticity of the walls and any undissolved

the pressure of the medium (elastomer seals). These sealing elements are predominantly elastic in fluid technology and made of elastomers or thermoplastics (materials for seals). In addition metal seals
