Abstract: A lockable hydraulic power-assisted steering system for steering one or more wheels of a vehicle, the system comprising: a hydraulic pump (1) having an inlet (2) and an outlet (3); a hydraulic reservoir (4) having an inlet (5) and an outlet (6); said pump inlet (2) being connected to the reservoir outlet (6); a hydraulic power steering housing (7a), the steering housing being operable by means of a steering wheel and the steering housing having an inlet port (8) and an outlet port (9); a hydraulic circuit, including: a pressure conduit connecting the pump outlet (3) to the steering housing inlet port (8), a return conduit connecting the steering housing outlet port to the reservoir inlet (5), a user operable lock valve (10) which selectively allows to connect and disconnect the steering housing inlet port (8) from the pump outlet (3) and/or to connect and disconnect the steering housing outlet port (9) from the reservoir inlet (5), characterized in that at the inlet port (8) of the hydraulic power steering ho

Abstract: The invention relates to a locking mechanism (1) for electromechanical protection of the hydraulic circuit of mechanically driven vessels/boats and vehicles, mostly trucks, but also private cars can be equipped with it, in which the steering gear and/or braking system can be blocked, in which a core cylinder (13) of the roughly 3/2-valve constructed locking mechanism (1) is operated by electronic control, in which in the driving position the mentioned core cylinder (13) is locked or blocked, in which the locking mechanism with accompanying electronic control (9) is mounted in a closed steel housing underneath the bonnet, which is also secured by the system and in which also an encoder unit (4) for further protection is provided, through which an optimally secure locking mechanism (1) against theft is created.
