Short term for hydraulic oils with additives designed to provide protection against ageing, corrosion and wear. Used where increased wear is expected, as may be the case when high levels of pressure a

Non-standardised short term used for hydraulic oils with additives designed to provide protection against ageing, corrosion and wear, as well as an additive with emulsifying (dispersing) and detergent

Term used for hydraulic oils with anti-ageing and corrosion-protection properties for systems subjected to a high thermal load. Viscosity index 95 to 105. (requirement standard DIN 51 524, Part 1).

Device for the oil mist lubrication of compressed air whereby lubricating oil is allocated directly to the load based on the quantity and impulse sequence and independently of the air flow. This favou

Reaction force generated if a fluid flow changes direction and/or velocity. The force F acts on the fluid from the outside as a supporting force. The force exercised by the flow on the environment is

Noise which contains short-lived and fast-rising changes in the of at least 5 to 10 dB (e.g. hammer blows, typewriters). Impulse noise is either measured using an impulse noise pressure meter or measu

Device which gives out pulses with a prescribed frequency at the output when a signal is pending at the input.

Signal generator, e.g. limit switches, limit pick ups, directional valves and the like, used to produce a pulse-like signal for a control process.

Indicates the quality of the pulse from a time perspective, e.g. rectangular pulse, sine pulse, among others.

Resistance of pressure hoses to pressure impulses. This is used — based on the max. permissible operating pressure — to determine the number of impulses required before the hose fails.
