A time delay valve includes a switching valve that switches between a first position and a second position; an urging member that urges the switching valve toward the first position; a driving mechanism that urges the switching valve toward the second position located opposite the first position in the presence of the pressure of a pilot fluid being supplied; a pilot flow channel that introduces the pilot fluid to the driving mechanism; and a delaying mechanism that delays the switching timing of the switching valve. The delaying mechanism includes a first throttle valve provided on the pilot flow channel, a compensation mechanism that urges the switching valve toward the first position in the presence of the pressure of the pilot fluid being supplied, and a compensation flow channel that is branched from the pilot flow channel to introduce a portion of the pilot fluid to the compensation mechanism.

Time delay valve and flow rate controller

Flow control valve

A flow controller that changes the flow rate of air exhausted from an air cylinder in mid-stroke includes a first switching valve displaced from a first position to a second position under the effect of pilot air, and causing one port of the air cylinder to communicate with a first channel at the first position, exhausting air exhausted from the one port of the air cylinder while reducing the flow rate of the air using a first regulating valve at the second position. Since the pilot air is taken into the first switching valve from a second channel in a system different from the system of the first channel, a second regulating valve can be adjusted without being affected by the degree of opening of the first regulating valve.

Flow controller and driving apparatus including the same

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.
