Said target high pressure is filtered, before being input, by means of a target high pressure filter which is configured as a dynamic target high pressure filter.

A discharge pressure value is smoothly brought close to a set pressure value, and fluctuation of the discharge pressure value reaching the set pressure value is reduced.

The deep fryer is also configured to drain under a setpoint pressure P2 lower than the setpoint pressure P1 the cooked foods.

A pressure adjustment screw allows adjustment of a set pressure of the pressure regulator.

Means are provided for calculating the set pressure of said valve.

In the method, the rail pressure is regulated, with a target high pressure being predefined.

To this end, a setpoint pressure gradient value is determined in the high-pressure accumulator as a function of the maximum possible actual pressure gradient value.

Overpressure: Generally, the set pressure is greater than the operating pressure.

The vessel (102) has a gas pressure regulator (132) in its interior volume, to maintain pressure of dispensed gas at a desired pressure determined by the set point of the regulator (132).

The target deformation of the compensation element, required to achieve a target pressure, is determined from the values calculated during said deformation and the compensation element is then placed around the substrate (10).

It may also be a pressure sensor which signals the deviation of the set pressure predetermined by the shield control device (5) from the measured actual pressure in the form of a deviation signal.

A set pressure value corresponds to a value of said very short time interval.

If acting on the high pressure valve set point, heat recovery has a direct effect on the lower limit for calculating the dynamic high pressure valve pressure control set point.
