DEFINITION

Classification: 137/565.01

With pump:

(under subclass 561) Subject matter wherein the system includes a pump that supplies energy to a fluid by suction or pressure or both. [figure] [caption]Figure 1: A typical example of the subject matter. A - Automatic washing machine system; B - Pump; C - Drain pipe; D - Drain hose.

(1) Note. The combination of a pump and a tank generally will be classified in this class (137). However, a single nominally recited tank reservoir, chamber, pump, or other similar fluid holding means will be classified elsewhere. See SEARCH CLASS notes below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13, for a process wherein the addition of material or energy effects the flowing fluid.

147+, for a pump or liquid displacement device for starting a siphon-type fluid handling system.

206+, for a gas and liquid containing system wherein the gas under pressure is employed to displace liquid.

282, for a hydrant-type fluid handling system having a pump or an ejector.

SEE OR SEARCH CLASS 222, Dispensing, Class Definition, (9) Note for other pump-tank relationships; and

372+, for a material supply container and a discharge assistant with casing including a pump.

417, Pumps, for a single nominally recited tank reservoir, chamber, pump, or other similar fluid holding means; see Class Definition, (3) Note;

46+, for a condition responsive pump drive motor by controlling drive motor motive fluid; and subclasses 279+ for condition responsive control of pumped fluid.

418, Rotary Expansible Chamber Devices, appropriate subclasses for a rotary expansible chamber pump, per se.
