Disclosed is a clothes treating apparatus including a drum configured to receive laundry, a tub in which the drum is built, a main body in which the drum and the tub are disposed, detergent drawer compartments provided in the main body to be withdrawn from or inserted in the main body, a spray nozzle configured to spray washing water to the detergent drawer compartments, a water-collecting container disposed below the tub to receive the washing water, a washing line configured to supply the washing water of the water-collecting container to the spray nozzle, a circulation line configured to supply the washing water of the water-collecting container into the drum, and a flow-path conversion pump configured to receive the washing water from the water-collecting container and supply the washing water selectively to the washing line or the circulation line.

In an aspect, a pump is provided and includes a pump housing having a pump inlet and a pump outlet. An impeller is rotatably supported in the pump housing for rotation about an impeller axis, and has an impeller inlet configured for drawing in liquid during rotation of the impeller, and an impeller outlet configured for discharging liquid in a generally radial direction. A diverter is pivotally connected in an impeller outlet receiving chamber in the pump housing. The diverter is movable between a first position in which it provides a first restriction to flow out from the pump housing and a second position in which it provides a second restriction to flow out from the pump housing that is greater than the first restriction. In the first position, the diverter forms at least a portion of a volute around at least a portion of the impeller.

A variable mechanical automotive coolant pump includes a rotatable rotor shaft, an impeller wheel which is co-rotatably connected with the rotor shaft, a static guiding cylinder, a control sleeve, and at least one guiding device. The impeller wheel has a discharging radial outside. The control sleeve has a hollow-cylindrical control sleeve body having a radial outside. The control sleeve does not rotate and is guided axially slidable within the static guiding cylinder so as to regulate a flow rate of the variable mechanical automotive coolant pump by closing or opening the discharging radial outside of the impeller wheel. The at least one guiding device guides the radial outside of the control sleeve within the static guiding cylinder.

The present disclosure provides a decorative cup. The decorative cup includes a shell. The shell includes a cup body and a base. The cup body includes an accommodating portion and a transparent portion. A cavity is formed in the base. The accommodating portion is disposed in the cavity. The transparent portion is made of a transparent material, and shaped as a polygon prism. The transparent portion may enable light rays to be reflected for multiple times on the cup body because of the polygon prism structure of the transparent portion, so that the cup body looks more crystal clear and more dazzling, thereby greatly improving the ornamental value of the decorative cup.

A method of operating a centrifugal pump (10) having a casing forming a volute (75) in which a rotatable impeller (20) is disposed for urging a fluid material (30) into the volute, the method comprising: monitoring a fluid pressure pulsation event inside the pump casing; generating, based on said monitoring, a vibration signal indicative of occurrence of said first fluid pressure pulsation event; generating a reference signal indicative of a rotational reference position of said rotating impeller; determining a temporal relation value (FI, FI(r)) based on time of occurrence of said fluid pressure pulsation event (SP(r)) and said reference signal.

A centrifugal pump with adaptive pump stages includes an impeller configured to provide kinetic energy to fluid flow through the pump. The impeller has multiple geometric dimensions. The pump includes a diffuser connected to the impeller that is configured to convert the kinetic energy provided by the impeller into static pressure energy to flow the fluid through the pump. The pump includes an adaptive material attached to the impeller that is configured to modify, during operation of the pump, a geometric dimension to modify fluid flow through the pump.

A mechanical coolant pump for an internal combustion engine includes an impeller pump wheel. The pump housing comprises an outlet valve arrangement arranged between an outlet volute and a pump outlet, and a support portion. The pump housing closes and/or opens a valve opening. The outlet valve arrangement comprises a valve body which pivots. The valve body comprises a closing element which covers the valve opening, and first and second end disks. The closing element comprises an opening seat in a closed valve position. The first and second end disks are parallel to each other, are arranged at opposite axial ends of, and perpendicular to, the closing element, and rotate around a pivot axis. The first and second end disks each comprise a radial clamping nose which acts with the support portion to radially push the closing element against the opening seat in a closed valve position.

A pump assembly is disclosed comprising a pump including a pump housing having a fluid inlet conveying fluid to a pump cavity At least one fluid outlet extends from the pump housing. A plurality of fluid outlet ports extend from the pump housing. An impeller driven by a motor drives the fluid in the pump cavity. In a first embodiment, a valve member rotatably mounted between the impeller and the plurality of fluid outlet ports is arranged to selectively direct the flow of fluid from the pump cavity to one or more of the plurality of fluid outlet ports. In a second embodiment, the valve member includes a first and a second wall between a first and a second opening. The first and second openings are arranged to direct the flow of fluid from the pump cavity to at least two of the plurality of fluid outlet ports.

A method of operating a centrifugal pump (10) having a casing (62) in which a rotatable impeller (20) is disposed, the rotatable impeller (20) having a number (L) of vanes for urging, when the rotatable impeller (20) rotates, the fluid material (30) from a pump inlet (66) into the volute (75), the method comprising receiving a vibration signal (S.sub.EP; S.sub.EA, S.sub.MD, Se(i), S(j), S(q)) dependent on a fluid material pulsation (V.sub.p); receiving a signal (E.sub.p, P(i), P(j), P(q)) indicative of a rotational position of said rotatable impeller (20) in relation to said casing; generating, based on said vibration signal and said position signal, information indicative of an internal state of the centrifugal pump (10).

A method of operating a centrifugal pump (10) having a casing forming a volute (75) in which a rotatable impeller (20) is disposed for urging a fluid material (30) into the volute, the method comprising: monitoring a fluid pressure pulsation event inside the pump casing; generating, based on said monitoring, a vibration signal indicative of occurrence of said first fluid pressure pulsation event; generating a reference signal indicative of a rotational reference position of said rotating impeller; determining a temporal relation value (FI, FI(r)) based on time of occurrence of said fluid pressure pulsation event (SP(r)) and said reference signal.
