Combined piston

Above all on pressure valves the closing element (cone or piston) has a damping piston to prevent undesirable oscillations (chattering) (Figure D 3) . It must be designed such that the damping is only

English unit of pressure. Conversion: 1 bar = 14.5 psi and 1 psi = 0.07 bar (i.e. 1 000 psi = 70 bar).

Filter whose filter element contains paper made of natural or artificial fibres. Depending on the form involved, a distinction is made between star-shaped paper filters and wound paper filters.

All oscillations which are not harmonic, i.e. which are not periodic sine oscillations with a given frequency. A typical form of anharmonic oscillation is noise .

Lower limit for a pressure value at which a device or system will still be functional (DIN 24 311).

Uses the velocity of the flowing medium to rotate a paddle wheel when the flow is in an axial direction ( Figure M 21 ). The turbine rotation speed in such cases is used to measure the passing flow ra

Operating mode whereby a machine is controlled using manually operated valves. These days, the only area where manual operation is still predominant is mobile hydraulics . In addition, the term manual

Describes the state whereby the relationship between two adjustable variables remains constant.
