Fluid level height above an inlet or outlet opening. In the case of a negative inlet height, the suction pressure for pumps is lower than the ambient pressure (Figure Z 8).

Hydraulic pump in which the pressure fluid is displaced by one or more pistons . Pistons may be arranged in a row or aligned radially or axially in relation to the drive shaft.

Characteristic whereby every genuine fluid reduces in volume under pressure. The compressibility associated with mineral oil is also dependent on the temperature and the kind of change of state involved

Gas pressure that is applied to a fluid vessel with or without separator. On hydraulic accumulators the gas filling pressure corresponds to the precharge pressure. Example: hydropneumatic accumulator

Non-contact seal from the group of labyrinth gap seals on which fluid flowing outward is pumped back by a counter-rotating thread on the shaft. Here a pointed, triangular thread has proven effective (Figure

Control system on which the operating position is separate from the fluid technology systems such that the operating elements need to be operated over a greater distance. Operation can be using both hydraulic

standards institutes whose technical committee TC 131 works on all standardisation tasks associated with fluid technology. The resulting ISO standards are either adopted directly (DIN ISO ...) or incorporated

Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in the form of a seated valve or ball valve . The valve is actuated manually, magnetically or using a

hardness. However, it is also affected by the temperature and the degree of exposure to the hydraulic fluid (swelling or shrinkage).

reduce the speed of a piston before the end of its stroke. The damping can be mechanical or using a fluid; a choice can be made between fixed or adjustable ( Damping of cylinder motion ).
