A disk valve for a fluid under pressure, inside a housing (10), and comprising one, fixed plate cam (26), which has one port (32). A second, rotatable plate cam (34) which also has a port (36) is mounted above the fixed disk cam (26). The ports (32, 36) are eccentric to the axis of rotation of the rotating disk cam (34) such that they can be brought from an aligned open position into a misaligned closed position by rotating the rotating plate cam (34). A pressure relief surface (44, Ae), concentric to the axis of rotation, is provided on the rotating plate cam (34) and this surface is in contact with the outlet pressure of the fluid, in the closed position at least. To compensate the tilting moment which is exerted on the rotating plate cam (34) due to the off-centre position of the port (32) in the fixed plate cam (26), a slot (74) is made in the upwards facing surface of the fixed plate cam (26) which, in its position and shape, is approximately symmetrical to the cross-sectional form of the port (32) and, for its part, is in contact with the outlet pressure, in the closed position at least.

Disk valve

An arrangement for driving the traveling flats of a carding machine. A drive gear is readily releasably secured to the carding machine at one end of the flats for driving the flats in one revolving direction and, for driving the flats in another revolving direction, the drive gear is removed from the one end of the flats and readily releasably secured at the other end of the flats.
