to an excessive load on the output element, i.e. the valve acts from p 1 to p 2 as a pressure-reducing valve and from p 2 to p 1 as a pressure-limiting valve . Pressure-reducing valves can be directly [...] Valve that keeps the (lower) outlet pressure (secondary pressure) p 2 constant even with changing inlet pressure (primary pressure) p 1 . This action is achieved by a valve cone, held open by a spring, that

the area of this surface A ( DIN 24 312 ): The derived unit for pressure in the SI system is the pascal: 1 Pa = 1 N/m2. In fluid technology p is mostly stated in bar (1 bar = 105 N/m2). However, MPa (106 N/m2)

Hydraulic pump with constant geometric displacement V 1 for each revolution and therefore a constant delivery flow Q 1 at constant drive speed n 1: Q 1 = V 1 · n 1.

1. Term previously used instead of " nominal size " to indicate a device size. 2. Standardised numerical variables with which the inside diameter of pipes is compared. The nominal width for pipes is defined

Modified HLPD oils that only take on (hold) a water content of 1 to 2%, but separate larger water quantities –– like any normal mineral oil . The stabilised hydraulic oils therefore only slightly reduce

corrosion and wear and with viscosity improvement additives (Figure H 10) ; viscosity index: type 1: 125 to 190; type 2: 240 to 400. (requirement standard: DIN 51 524, Part 3)

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

delivered flow rate ( displacement volume V 1, drive rotation speed n 2 ): For motors: Theoretically absorbed flow rate Q 2th ( displacement volume V 2, rotation speed n 2 ) to effectively absorbed flow rate.

The flow rate is then the product of the chamber volume, number of gears and rotation speed (Figure Z 1). The accuracy of the gear pump flow meter depends on the leakage in the gears; it is around ±0.5 %

g. a Prandtl tube ( Figure S 78 ). This is then used to measure the static pressure p 1 and the dynamic pressure p 2 and thereby calculate the flow rate from the
