Abstract
The invention relates to an arrangement and a method, the method comprising—uncoupling a mechanical coupler (M), —activating a first valve (2, 20) in response to the uncoupling of the mechanical coupler (M) by switching the first valve (2, 20) to a first state, —activating a valve unit (3, 30), —connecting an uncoupling control inlet (A) of the valve unit (3, 30) to a first valve unit outlet (34, 305) in response to the activation of the valve unit (3, 30), said uncoupling control inlet (A) being an inlet that is supplied by air from the MRP inlet (11), —deactivating an electrical coupler control device (6)—retracting the electrical coupler (E).

A method for uncoupling a coupler of a railway vehicle, the coupler comprising a mechanical coupler and an electrical coupler, the method comprising
- uncoupling a mechanical coupler (M) in response to an uncoupling command, activating a first valve (2, 20) in response to the uncoupling of the mechanical coupler (M) by switching the first valve (2, 20) from a second state to a first state, the first valve (2, 20) comprising a first inlet (21, 201) connected to an MRP inlet (11) configured to be connected to a main reservoir pipe of a rail vehicle, wherein the first state of the first valve (2, 20) is a position in which the first inlet (21, 201) is connected to a first outlet (23, 203) so that air is able to flow through the first valve (2, 20) to the first outlet (23, 203),
- activating a valve unit (3, 30) by receiving air from the first outlet (23, 203) of the first valve (2, 20) to a first valve unit inlet (31, 301), and switching a second valve (4, 420) of the valve unit (3, 30) to a first state, said first state being a position in which the uncoupling control inlet (A) is connected to the first valve unit outlet (34, 305),
- connecting an uncoupling control inlet (A) of the valve unit (3, 30) to a first valve unit outlet (34, 305) in response to the activation of the valve unit (3, 30), said uncoupling control inlet (A) being an inlet supplied by air from the MRP inlet (11),
- deactivating an electrical coupler control device (6) by receiving air from the first valve unit outlet (34, 305) to an uncoupling inlet (61) of the electrical coupler control device (6), and
- retracting the electrical coupler (E).
A pneumatic coupler control arrangement for controlling an uncoupling of a coupler for a rail vehicle, the coupler having a mechanical coupler and an electrical coupler, the pneumatic coupler control arrangement comprising
- a mechanical uncoupling device (5) for uncoupling a mechanical coupler,
- a first valve (2, 20) comprising a first inlet (21, 201) connected to an MRP inlet (11) configured to be connected to a main reservoir pipe of a rail vehicle for receiving pressurized air, the first valve (2, 20) further comprising a first outlet (23, 203) and a trigger (25, 205) for switching the first valve (2, 20) to a first state, wherein the first state is a position in which the first inlet (21, 201) is connected to the first outlet (23, 203), and the mechanical uncoupling device (5) is configured to activate the trigger (25, 205) in response to an uncoupling command,
- a valve unit (3, 30) comprising a first valve unit inlet (31, 301) operatively connected to the first outlet (23, 203) of the first valve (2, 20), wherein the valve unit (3, 30) comprises a first trigger (T1, 425) connected to the first valve unit inlet (31, 301) for activating the valve unit (3, 30) to switch a second valve (4, 420) of the valve unit (3, 30) to a first state, and the first state is a state in which an uncoupling control inlet (A) is connected to a first valve unit outlet (34, 305), said uncoupling control inlet (A) being an inlet supplied by air from the MRP inlet (11), and
- an electrical coupler control device (6) configured to extend an electrical coupler for coupling and retract the electrical coupler for uncoupling, wherein the electrical coupler control device (6) comprises an uncoupling inlet (61), said uncoupling inlet (61) connected to the first valve unit outlet (34, 305) and the electrical coupler control device (6) configured to uncouple an electrical coupler in response to receiving pressurized air to the uncoupling inlet (61).
