Abstract:

A cleaning apparatus for generating a pulsed liquid stream, comprising a fluid tight housing having a cylindrical side wall, and first and second ends being compact enough to be hand held by a user. A piston mounted in the housing forms a liquid tight seal with the sides of the housing and slides between a first and a second position in response to an actuation means operated by hand pressure. An output port in the second end of the housing is connected to a nozzle for directing liquid at a desirable location. A liquid control means connected between the output port and the nozzle receives pressurized liquid exiting through the output port and transfers discrete portions of the liquid to the nozzle forming a pulsative stream of liquid exiting the nozzle. The liquid control means can comprise a rod connected to the piston and extending toward the output port with a plurality of cylindrical plugs secured thereto at intervals determined by a desired length or fluid quantity for pulses in said pulsative stream, each plug having a length commensurate with desired periodicity for pulses in said pulsative stream, and a diameter as close to that of said output port as possible without preventing the movement through the output port. In addition, a liquid tight, flexible or static bladder for confining predetermined portions of a desired cleaning solution can be employed within the apparatus housing.
