Abstract
A nozzle mechanism (10) comprising a flexible barrel (13) annularly spaced about a fluid jetting tube (12) apertured as at (16) to a rear tubular portion (15), a manipulative sleeve (33) on the barrel (13), and a valve control member (24) to open and close its valve (28) aligned with aperture (16). Valve control member (24) includes a pin 29 operatively connected to the sleeve (33) via a slot (30) in barrel (13), so that manipulative motion of sleeve (33) opens and closes valve (28), as well as locking open valve (28) by reason of pin (29) being retained in a catch (31) on slot (30) in flexible barrel (13).
Claims20
A nozzle comprising
- a rear portion, an interior in the rear portion, and a tube having an aperture communicating with such interior,
- a flexible barrel spacedly mounted about and longer than said tube so as to provide an annular space about the tube and forming a dispensing chamber in front of said tube,
- slot means formed in said barrel,
- valve means disposed in said rear portion,
- a control member for said valve means being disposed in said rear portion and extending into the annular space about said tube,
- means mounted on said control member projecting through said slot means, and
- a sleeve manipulatively mounted on said barrel,
- said projecting means operatively connected to said sleeve,
- whereby manipulative motion of said sleeve with respect to said barrel unseats and seats said valve means with respect to said aperture.
A mechanism, adapted for a fluid jetting tube mounted on a rear interior portion adapted to connect to a fluid source, with an aperture communicating said fluid jetting tube with said rear interior portion,
- said mechanism comprising
- a flexible barrel disposed about said fluid jetting tube thereby forming an annular space and extending from said rear interior portion to beyond said fluid jetting tube,
- a valve disposed within said rear interior portion for seating and unseating on the aperture, and
- control means for seating and unseating said valve and disposed in said rear interior portion and extending from said rear interior portion into the formed annular space and further about said flexible barrel.
