Abstract: A valve body of a speed controller includes a main body that extends along a first axis and a mounting portion that projects from a side of the main body along a second axis that intersects the first axis orthogonally. A first port, a needle valve, and a check valve are disposed in the main body. The mounting portion, which is a portion to be mounted on a cylinder portion, includes a second port formed therein. A position at which the mounting portion is disposed on the side of the main body is away from the first axis in a direction of a third axis that orthogonally intersects the first axis and the second axis.

Abstract: A fluid control valve includes a first flow path and a second flow path that connect a first port and a second port in parallel. The first flow path includes an opening and closing valve mechanism that temporarily opens the first flow path. The second flow path includes a throttle valve mechanism that restrictedly opens the second flow path. The opening and closing valve mechanism includes an opening and closing valve portion including an opening and closing valve seat and an opening and closing valve body, a valve opening force generator, and a delay valve closing mechanism that closes the opening and closing valve body after a delay time has elapsed. The throttle valve mechanism includes a throttle valve portion. The opening area of the opening and closing valve portion is larger than the opening area of the throttle valve portion.

Abstract: An apparatus for cleaning printing cylinder comprising a cleaning head 3 is disposed in parallel to the printing cylinder so as to be attachable and dettachable to the overall width thereof, and the cleaning is carried out by pressing said cleaning head 3 against the printing cylinder 1. The cleaning head 3 comprises a cleaning case 9 having a suction port 8 at the upper part thereof and a wind chest 10. The interior of the cleaning case 9 is partitioned into the front 11, the rear 12, and the middle part 13 with respect to the direction of the rotation of the printing cylinder 1, with the front 11 and the rear 12 being, respectively, fitted with cleaning members 14, 15 and the middle part 13 being fitted with a lip 16 composed of an elastomeric material. Between the lip 16 and the front 11 and beneath the rear 12 there are formed slits 17, 18 which have suitable gaps, and both of them communicate with the wind chest 10.
