Abstract:
1. A rotary valve ( 10 ) for distributing a flow of a fluid, the valve comprising a stator ( 11 ) and a rotor ( 12 ), wherein said stator ( 11 ) comprises at least eight ports protruding into the stator and each port ending in a corresponding orifice on an inner stator face ( 11 a ), wherein a first port ( 21 a ) ends in a first orifice ( 21 b ), a second port ( 22 a ) ends in a second orifice ( 22 b ), a third port ( 23 a ) ends in a third orifice ( 23 b ), a fourth port ( 24 a ) ends in a fourth orifice ( 24 b ), a fifth port ( 25 a ) ends in a fifth orifice ( 25 b ), a sixth port ( 26 a ) ends in a sixth orifice ( 26 b ), a seventh port ( 27 a ) ends in a seventh orifice ( 27 b ) and an eighth port ( 28 a ) ends in an eighth orifice ( 28 b ), the inner stator face ( 11 a ) being a face of the stator making contact in a fluid tight manner with an inner rotor face ( 12 a ) of the rotor ( 12 ), said inner rotor face ( 12 a ) being rotatably movable around a rotational axis (RA) relative to the inner stator face ( 11 a ), each one of said stator orifices ( 21 b - 28 b ) being distributed around the rotational axis (RA) at a common radial distance R, further wherein the first, second, third and fourth orifices ( said inner stator face ( and wherein said inner rotor face ( to allow the stator ( wherein in the first position there is fluid communication between the first port ( in the second position there is fluid communication between the first port (
