    Abstract: A flow control system (1) for a fuel injector for an internal combustion engine is provided comprising an inlet port (2), an outlet (3), a return port (4), a 2- way control valve (40) comprising a control valve member (6), a shuttle valve (43) and a main valve (44). The control valve (40) comprise a first seat (7), a first resilient means (16) configured to force said control valve member (6) towards the seat (7) so as to close the control valve (40), and a first abutment (8) that limits the lift of said control valve member (6) away from said first seat (7). The first seat (7) of the control valve (40) is slidably arranged in the shuttle control chamber (10). An end stop (20) for the first seat (7) is provided such that the pressure in a shuttle control chamber (10) tends to move said first seat (7) towards said end stop (20). The first seat (7), upon its mechanical contact with a valve member (6) is able to transmit at least a part of the force of the resilient means (16) onto a shuttle valve body (9) in the opening direction of the shuttle valve (43).

    Abstract: The invention is related to a vehicle with a driver's cab (10) comprising a driver seat unit (17) with a vertically suspended floor structure (17a) including means for steering control (15), means for speed control and a driver's seat (13). According to the invention, the cab (10) is provided with a locking mechanism for preventing the floor structure (17a) from moving vertically in relation to the cab (10) when the vehicle is immobile. Further the floor structure (17a) is able to move from a first position to a second position, lower than the first position, when the driver's door (12) is opened and to move back to the first position when the driver's door (12) is closed.

    Abstract: The invention relates to a method for controlling a traction system (1) for a heavy road vehicle. The system comprises a first mechanical propulsion system (12), a second hydraulic propulsion system (13) and a control unit (9). The method comprises the steps of measuring a first parameter value, indicative of the rolling radius of a first traction wheel (2a, b), measuring a second parameter value, indicative of the rolling radius of a second traction wheel (6a, b) and said control unit (9) using said first and second parameter values for determining a present relation between the rolling radii of said first and second traction wheels (2a, b; 6a, b). Finally, the control unit (9) provides an output signal based on said present relation to optimize the traction applied to said second traction wheel (6a, b). The invention also relates to a traction system (1) and a heavy vehicle incorporating a traction system (1).
