Standard measure for the hardness of elastomers , in which the penetration depth is measured in a test specimen. A distinction is made between Shore A for softer specimens (up to approx. 90 Shore A) a

Slowly approaching a position. This is used in feed mechanisms with a high rapid traverse speed directly before the position is reached in order to achieve optimal position accuracy ( Figure S 28 ).

Depending on the requirements placed on the switching characteristics of a valve (e.g. to prevent switching shocks), the switching speed for the intended actuation element must be slowed down. This ge

2-way which ensures for load sensing systems based on several different loads connected in parallel that the load sensing pressure difference remains constant at the metering orifice regardless of the

When selecting a filter, the key parameters of filter fineness , dirt holding capacity, and the Pressure difference on the filter should be taken into consideration. During the evaluation, it is not s

Is produced on changing from the suction side to the pressure side on hydrostatic displacement machines . Due to the pressure drop or increase that occurs in a very short time. The process is all the

Flow rate which continues to flow for proportional valves, high response proportional valves and servo valves when the consumer ports are closed and at a system pressure p o. It results from the leaka

Hydraulic (pressurised) actuation of a valve by a small, directly solenoid actuated valve (pilot valve). Here the pilot valve is mostly directly on the main valve (Figure E 19) . With this combination

The oil samples needed to check the degree of contamination of hydraulic fluids must be taken in compliance with highly specific guidelines or the measurement results will not be representative for th

(Opposite of pilot valve). With pilot-controlled valves, the main valve is the actual working valve actuated by the pilot valve .
