reservoir is calculated from the temperature difference between the reservoir and the ambiance (To – Ta), form the heat-emitting area A of the reservoir and the heat transfer coefficient U (~11...15 W/(m²·K)

column + load) and the pressurisation at very low sliding speeds ( Figure S 94 ). The stiction of the system –– which is primarily determined by the seals used — is a determining variable. The smaller [...] smaller it is, the smaller the velocity, at which it can still run smoothly. As the friction also depends on the pressure, that too is an influencing factor: the higher it is, the greater the stiction and sliding

drive shaft with one pump as a drive for a second pump ( Figure V 20 ) — in this case both are adjusted using a sum power controller — or a transfer case is used for both pumps, which are then adjusted i

with constant pumps the flow rate not required Q V (Q V = Q 1 – Q N) is fed back to the tank (Figure D 47) . The power converted into heat at the throttling point on the 3-way flow control valve is proportional [...] proportional to the product of Q v and the load pressure p L: With all other methods (that is also with continuously adjustable valves) Q v must be reduced via the pressure-limiting valve , i.e. under full

oil flow is multiplied by the indexing ratio, therefore in practical use, an indexing ratio of up to 4:1 is still reasonable.

flow rate Q is calculated from the temperature difference at inlet and outlet, the specific heat capacity of the medium c (~1.88 kJ/(kg*K) for Oil, ~4.18 kJ/(kg*K) for water) and the density of the medium

possible to achieve a complete seal with it — not least because of the inevitable impact involved. The seal effect can be improved, however, if the impact occurs at an angle or in stages and by installing

t motor , ( primary control ), constant pump variable motor ( secondary control ) or variable pump — variable motor ( primary and secondary control ).

The back pressure

2 or F 1 = p 1 * A 1 and F 2 = p 2 *A 2 This surface area ratio also defines at the same time the transmission ratio of the pressure amplifier. It is possible to operate with the same pressure fluid and [...] pressure p 1 of the primary pressure system is brought to a higher pressure p 2 in the secondary system. The pressure boost factor is given by the ratio of the primary and secondary surface areas: F 1 = F 2
