Abstract: A bus-repeater for coupling at least one first bus with a second bus, by way of which data may be transmitted in the form of serial digital signal pulse sequences and including at least one first and a second transmit-receive device, with which the first and, respectively, the second bus may be coupled and by way of which the bus-repeater may transmit signal pulse sequences, received via the first bus on the second bus, and vice versa. In accordance with the invention the bus-repeater includes locking device, which during transmission of a signal pulse received from the first bus to the second bus lock transmission by the bus-repeater of signal pulses, received from the second bus, via the first bus for a transmission locking time and vice versa.

Abstract: A fluid power arrangement and valve arrangement (12) with an actuator (10) for it. The actuator (10) is able to be operate by means of the valve arrangement (12) via at least one first and first second fluid line (13 and 14) using fluid power, at least one electrical component (37, 38 and 46), adapted for connection with a control module (39 and 61), being arranged on the actuator (10).

Abstract: A bus-repeater for coupling at least one first bus with a second bus, by way of which data may be transmitted in the form of serial digital signal pulse sequences and including at least one first and a second transmit-receive means, with which the first and, respectively, the second bus may be coupled and by way of which the bus-repeater may transmit signal pulse sequences, received via the first bus on the second bus, and vice versa. In accordance with the invention the bus-repeater comprises locking means, which during transmission of a signal pulse received from the first bus to the second bus lock transmission by the bus-repeater of signal pulses, received from the second bus, via the first bus for a transmission locking time and vice versa.
