A pressure control device for a vehicle tire inflating system is configured to receive compressed air via a ventilating inlet, activate at least one seal for sealing an air chamber between a stator and a rotor of a rotary feedthrough via a seal actuating outlet, and ventilate a tire at a ventilating outlet pressure via a ventilating outlet and the feedthrough. A control valve is pneumatically controllable by a control pressure, the ventilating outlet being ventilated at the outlet pressure by the control valve only when the control pressure is at least a defined minimum pressure. In response to pressure build-up at the ventilating inlet at least to the minimum pressure, the control pressure and the seal actuating pressure are built up for ventilating, but build-up of the control pressure is delayed with respect to the seal actuating pressure. Activation of a seal prior to ventilation of the ventilating outlet is possible without additional actuating channels.

摘要:
A process for braking a vehicle having at least first and second brakes, comprises supplying energy to the first and second brakes so as to actuate them, the energy being distributed between the first and second brakes in accordance with the brakes' response energies. Preferably, the momentary values of the response energies are used so that the first and second brakes are actuated simultaneously. The momentary values of the response energies of the brakes may be determined as follows: (a) measuring the existing vehicle deceleration to determine a value of ground-vehicle deceleration, (b) supplying a braking test energy to the brake being tested, (c) measuring the deceleration of the vehicle after the braking test energy has been supplied to the brake being tested in order to determine a value of vehicle test deceleration, (d) comparing the value of ground-vehicle deceleration with the value of vehicle test deceleration, and (e) if the value of vehicle test deceleration is greater than the value of ground-vehicle deceleration by more than a predetermined tolerance value, repeating steps (a) to (d) with a reduced braking test energy until the difference between the value of vehicle test deceleration and the value of ground-vehicle deceleration is decreased to no more than the predetermined tolerance value, or (f) if the value of vehicle test deceleration is equal to or less than the value of ground-vehicle deceleration, repeating steps (a) to (d) with a higher braking test energy until the value of vehicle test deceleration exceeds the value of ground-vehicle deceleration by a value which is less than or equal to the predetermined tolerance value. The energy supplied to the brakes to actuate them may be in the form of pressure.
