A self-cleaning plunger includes an elongate cylindrical handle; a fluid reservoir clamped to the handle; a pump housed within the handle; and a resilient plunger cup coupled to a fluid dispersing sprayer assembly. A grip is formed around one end of the handle and the fluid dispersing assembly is coupled to the other. The fluid reservoir communicates fluid to the pump which communicates fluid to the dispersing assembly. The cup has a central aperture and the sprayer assembly is coupled to the handle. The sprayer assembly has an upper component with spray nozzles to direct spray toward a convex surface of the cup and a lower component extending through the central aperture to direct spray toward a concave surface of the cup. A method of cleaning a plunger with the self-cleaning plunger includes putting cleaning fluid in the fluid reservoir and actuating the pump.

A system comprises a gas turbine engine including a compressor, combustor, gas turbine, the combustor including a plurality of late lean fuel injectors; and wash system configured to be attached to and in fluid communication with the a plurality of late lean fuel injectors of the combustor. The wash system includes a water source supplying water; a first fluid source supplying a first fluid; a mixing chamber in communication with the water source and first fluid source; a water pump to pump water to the mixing chamber; a first fluid pump to pump the first fluid to the mixing chamber; a fluid line in fluid communication with the mixing chamber and at least one of the plurality of late lean fuel injectors so fluid from the mixing chamber is injected into the combustor at late lean fuel injectors. The wash system is operated with the gas turbine engine off-line.

A hydraulic arrangement (HA) for an apparatus (AV) for deblocking optical workpieces (L), from associated block pieces (B), includes a nozzle arrangement (DA) for delivery of high pressure jets of pressure means for deblocking the workpiece from the associated block piece at a first pressure and for cleaning the blocked workpiece and/or block piece at least one second pressure which is different from the first pressure. Furthermore, there is a pump device (PE) which applies pressure in a defined manner to the pressure means and conveys it under pressure to the nozzle arrangement. The pump device has at least one high pressure pump (HP1, HP2) which is drivable by an associated rotary drive (SM1, SM2), the speed of which is modifiable in order to adjust the first pressure or the second pressure.

A combined cleaning and wringing system, including a mopping device including a cleaning textile to be cleaned and wrung, a cleaning station, and a wringing station. The cleaning station and the wringing station are spatially combined in a housing and the cleaning station includes a cleaning fluid tank filled with a cleaning fluid, a pump and at least one spray head. The cleaning fluid tank, the pump and the spray head are in fluid communication and the wringing station includes at least one scraper having at least one scraper lip, across which the cleaning textile can be passed. The cleaning station and the wringing station are functionally separate, in that the cleaning fluid tank is only associated with the cleaning station, the wringing station includes a wastewater tank only associated with the wringing station, and there is no fluid communication between the wastewater tank and the cleaning fluid tank.

A pressure washer includes a main line through which, via a high-pressure pump, liquid can be conveyed to a spray opening, and a main valve. The main valve, when in a closed state, prevents liquid from flowing through the main line and, when in an open state, allows liquid to flow through the main line. The main valve is switchable between open and closed via an operator-controlled element. The main line has a suction chamber between the connection and the pump and a pressure chamber between the pump and the spray opening. The pressure chamber is fluidically connected to the suction chamber via a bypass line. A free cross-sectional area of the bypass line is settable via a bypass valve in the bypass line for regulating pressure in the pressure chamber. The bypass valve is adjustable via the operator-controlled element for setting the free cross-sectional area of the bypass line.

The food processing system according to the present invention comprises: a transport unit for continuously transporting food; a processing unit through which the transport unit passes and which is provided with an internal space for processing food transported by the transport unit; and a cleaning unit provided with a plurality of nozzles for spraying the internal space with liquid, either cleaning material or cleaning water, to clean the interior of the processing unit, and a liquid supply module for selectively supplying the plurality of nozzles with either the cleaning material or cleaning water.

A manually operated pressure fluid device has a housing structure which receives a motor-pump group and has a fluid inlet connected to the pump on the intake side and a fluid outlet formed on a nozzle unit and connected to the pump on the delivery side, an electrical power source and a control element acting on the power supply of the motor. The motor of the motor-pump group is a brushless DC motor and the pump is a whirling rotor pump having two lock washers, each having an annular face spline, where the number of teeth of the two face splines intermeshing with each other differ from each other by one and the lock washers arranged at an angle relative to each other wander relative to each other such that the face splines delimit a plurality of pump chambers which increase and reduce in size during pump operation.
