Abstract (en)
[origin: WO2019201579A1] In a mobile stretcher, in order to change the height position of a patient support mounted on a chassis, the geometry of the chassis is modifiable by means of a hydraulic drive system. The latter comprises a linear actuator, a pressure supply unit, and a receiving space for hydraulic fluid, and it moreover has a manually actuatable unlocking valve unit (14) for the direct connection of a stroke working space of the linear actuator to the receiving space for hydraulic fluid. The unlocking valve unit (14) has a control space (28), which is delimited by a piston element (30) guided movably relative to the housing (21) of the valve unit and which communicates with the stroke attachment (23) communicating with the stroke working space. The piston element (30) is operatively connected here to a valve body (27) which interacts with a valve seat (26) of a relief valve (16) configured between the stroke attachment (23) and a tank attachment (25) communicating with the receiving space (6). Moreover, a mechanical actuation input (35) of the valve unit (14) acts on the valve body (27), with interpositioning of a spring element (40).
