Oral irrigator handle assembly having a pressure control valve and stop valve assembly

A handle assembly for an oral irrigator, comprising:

• a housing;
• a pressure control valve, comprising:
• a valve body having an input section defining an input fluid flow path, an intermediate section having a substantially cylindrical bore therethrough, and a output section defining an output fluid flow path, said input fluid flow path fluidly coupled to said output fluid flow path through said bore;
• a valve gate having a cylindrical portion, a guide portion, and a control arm having a first end coupled to said cylindrical portion and having a second end a coupled to said guide portion, said cylindrical portion having an orifice bored therethrough;
• and
• a slide control positioned on the housing, the slide control being coupled to guide portion of the valve gate, so that as the slide control moves linearly along a portion of the housing, the cylindrical portion of the valve gate correspondingly rotates within the bore of the valve body.

An oral irrigation system for delivering pressurized fluid along a tube to a jet tip, comprising:

• handle assembly having a housing adapted to receive the jet tip, said handle assembly having a fluid input adapted to be coupled to said tube and a fluid outlet port adapted to be coupled to the jet tip, the handle assembly comprising:
• a pressure control valve, comprising:
• a valve body having an input section defining an input fluid flow path, an intermediate section having a substantially cylindrical bore therethrough, and a output section defining an output fluid flow path, said input fluid flow path fluidly coupled to said output fluid flow path through said bore;
• a valve gate having a cylindrical portion, a guide portion, and a control arm having a first end coupled to said cylindrical portion and having a second end coupled to said guide portion, said cylindrical portion having an orifice bored therethrough;
• and
• a slide control positioned on the housing, the slide control being coupled to guide portion of the valve gate, so that as the slide control moves linearly along a portion of the housing, the cylindrical portion of the valve gate correspondingly rotates within the bore of the valve body.

A pressure control valve for a handle of an oral irrigation device, said handle comprising:

• a valve body having an input section defining an input fluid flow path, an intermediate section having a substantially cylindrical bore therethrough, and a output section defining an output fluid flow path, said input fluid flow path fluidly coupled to said output fluid flow path through said bore;
• a valve member positioned in said cylindrical bore and rotatable therein, the valve member having an orifice bored through;
• and
• a slide control coupled to the valve member, so that as the slide control moves linearly, the valve member rotates within the bore of the valve body.
