Zusammenfassung:PURPOSE:To provide a rotary valve where a load to be exerted on a rotor shaft or a bearing can be reduced and the size can be reduced as a whole. CONSTITUTION:This rotary valve is provided with a pair of rotor casings 3a, 3b connected to each other, with an outlet 6 and an inlet 4 connected to each other; rotors housed in respective rotor casings 3a, 3b and having numerous pockets 22 at the outer peripheral surface thereof; a pair of equalizing pipes 42, 44 in each of the rotor casings 3a, 3b for communicating the pockets 22 with each other so as to equalize pressures; and another equalizing pipe 48 for equalizing pressures of the pockets 22 at a stage immediately before the corresponding pockets 22 are connected to the outlet 6 and the inlet 4 in the mutually connected state between the pair of rotor casings 3a, 3b.
