#CMT# #/CMT# The device (20) has a pump (21) provided with two bidirectional flow outlets (22, 23). Two supply conduits (26, 27) connect each outlet to corresponding hydraulic actuators, respectively. A hydraulic accumulator (30) is connected to the pump. A hydraulic distribution unit (31) with three inlets (31.1-31.3) moves among three positions, where the first inlet is connected to the hydraulic accumulator. The outlets are connected to the second and third inlets, respectively. A pressure controller (33) is arranged on a pipe (34). #CMT# : #/CMT# Independent claims are also included for the following: (1) a method for controlling two hydraulic actuators to operate an opening frame of a vehicle (2) a vehicle. #CMT#USE : #/CMT# Device for controlling two hydraulic actuators to operate an opening frame e.g. sliding roof and boot lid, of a vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The hydraulic accumulator is connected to the pump and carries out compression and decompression of a fluid i.e. gas, using a part of energy provided by the pump when the opening frame is in normal position, and the decompression of the fluid provides hydraulic power that can be used by a pilot circuit of the hydraulic actuators to reverse or stop movements of the opening frame immediately, thus avoiding risk of pinching and increasing safety of passengers in the vehicle in a simple and reliable manner. The pressure controller is arranged on the pipe, thus ensuring sufficient pressure condition of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a device for controlling two hydraulic actuators to operate an opening frame of a vehicle. 20 : Controlling device 21 : Pump 22, 23 : Bidirectional flow outlets 26, 27 : Supply conduits 30 : Hydraulic accumulator 31 : Hydraulic distribution unit 31.1-31.3 : Inlets 33 : Pressure controller 34 : Pipe. |
