A dish washing machine includes a plurality of spray nozzles to spray wash water, a sump to store wash water, a pump to pump wash water stored in the sump, and a distribution device to distribute wash water pumped by the pump into the plurality of spray nozzles. The distribution device includes a cylindrical housing having an inlet formed in one axial end portion thereof and a plurality of outlets that are arranged in a circumferential surface of the cylindrical housing in an axial direction and connected to the plurality of spray nozzles, an opening/closing member rotatably disposed within the cylindrical housing to open and close the plurality of outlets, and a motor to rotate the opening/closing member. Wash water may be independently sprayed from a plurality of nozzles, a wash tank may be dividedly washed, and loss of pressure of wash water may be reduced, thereby increasing washability.

An adjustable multiple bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. A valve member is disposed within the outer bladder and divides the outer bladder into two distinct inflation chambers. The inflation chambers may be inflated separately.

A rotary valve 1 comprising a stator 3 and a rotor 5, wherein the stator comprises a plurality of connection ports (17a-17l) and orifices (19a-19l) and the rotor comprises a plurality of pairs of rotor valve orifices (23a-23h) joined by transfer channels (25a-25d). The rotor is able to be placed in different working positions whereby fluids can be fed to, for example, chromatography columns and/or can be bypassed through or around the valve. The invention also relates to a system comprising two components such as chromatography columns and a rotary valve.

A system for controlling plurality of pistons in a corresponding plurality of actuators comprises a pump, a tank and a cylindrically shaped valve. The cylindrically shaped valve comprises an outer hollow cylinder with a first, a second, a third and a fourth set of holes, and the inner cylinder with a cylindrical base, and having a first and a second set of non-overlapping spiral grooves that are parallel to each other, in that the first set of holes are at different distance from the cylindrical base, the third set of holes maintain one to one correspondence with the first set of holes at 180 degrees opposite, the second set of holes maintain one to one correspondence with the first set of holes at same distance in a straight line, 180 degrees, the fourth set of holes maintain one to one correspondence with the second set of holes, 180 degrees opposite.

A rotary valve is disclosed. The valve comprises a drive shaft, a rotor coupled to the drive shaft, a least one bearing surface coupled to the rotor, a stator adjacent to the rotor, at least one solid bearing surface coupled to the stator, and at least one ring bearing surface coupled to the stator.

A rotary multi-port valve having a valve body defining a valve chamber and having a plurality of inlet flow ports each having a stationary seat member therein and having a discharge port. A flow diverter member is supported by a valve stem and a tubular trunnion for rotation within the valve chamber and has a diverter chamber. A piston is hydraulically moveable within the diverter chamber and has driving connection with a diverter valve member is linearly moveable for sealing engagement with a selected stationary seat member. The diverter valve member is selectively retracted to a position completely within the valve chamber to permit selective rotation of the flow diverter member within the valve body to an aligned position with any of the inlet ports of the valve body.

A valve device includes a housing, a flow hole forming portion and a rotor. The housing has a passage for fluid. The flow hole forming portion is fixed at the passage and includes: a plurality of flow holes, each of which is configured to conduct the fluid; and at least one partition which is placed between corresponding adjacent two of the flow holes. The rotor includes a passage opening and a closing portion. The at least one partition of the flow hole forming portion has: a parallel portion which extends in parallel with a radial direction of an imaginary circle centered on a rotational axis; and a progressively varying portion which is placed on an outer side of the parallel portion in the radial direction. A width of the progressively varying portion measured in a circumferential direction is progressively increased toward the outer side in the radial direction.
