Abstract: In a water jet massaging apparatus having a tub which is covered by a flexible elastic support sheet or foil for supporting a patient and a nozzle carriage with a nozzle and carriage drive arrangement disposed in the tub below the support sheet or foil for directing a water jet onto the support sheet, a rigid or at least non-elastic support element is disposed between the flexible elastic support sheet or foil and the nozzle carriage at a distance from the flexible elastic support sheet or foil so as to prevent the flexible elastic support sheet to come into contact with the nozzle carriage and the carriage drive arrangement.

Abstract: In a nozzle carrier drive for water let massaging apparatus a nozzle carriage which is movable along a guide track in the longitudinal direction of a tub of the water massaging apparatus and on which a nozzle for emitting a massaging water jet is disposed, a nozzle carriage drive arrangement is provided for independently moving the massaging water jet in the longitudinal and transverse directions of the tub by drive motors which are arranged outside the tub.

Abstract: A method for controlling a valve for maintaining brake pressure in a specified region of a brake circuit in a motor vehicle, in which the valve is controlled using a first control method, the specified region of the brake circuit is monitored with respect to the occurrence of a loss of brake pressure, and in response to a detected loss of brake pressure, the valve is controlled using a second control method.

Abstract: To achieve a specifiable, and thus reproducible final pressure in at least one part of the brake circuit, the pump is first actuated for pressure buildup or pressure reduction when the valve is closed. When a first specified setpoint pressure is reached, or when a pressure threshold value is exceeded, the valve is put into an open position using a first actuation. After the pump is switched off, the actuation of the valve is modified in such a way that, during a specifiable time, a continuous change of the first actuation is undertaken all the way up to a second actuation, in which the valve assumes a holding position, particularly while taking into consideration the pressure difference which prevails at the valve.
