Handgun and hose assembly for dispensing liquids

A handgun and hose assembly for dispensing liquid, the assembly comprising:

• a hose including an end portion for conveying said liquid,
• a nozzle coupled for fluid communication with the end portion of said hose;
• a valve member operatively connected with said nozzle and movable between open and closed positions to selectively allow and prevent liquid flow through said nozzle;
• a straight, tubular gripping portion extending generally along an axis and coupled in generally surrounding relation to the end portion of said hose;
• and
• an actuation member including a manually operable actuating portion coupled to said valve member for moving said valve member between said open and closed positions, wherein said gripping portion, said actuating portion and the end portion of said hose each extend generally parallel to one another to allow gripping and actuation by a user in multiple hand and hose orientations and said actuating portion is rotatable at least partially around said gripping portion and said axis.

A handgun and hose assembly for dispensing liquid, the assembly comprising:

• a hose including an end portion for conveying said liquid;
• a handgrip carried by said hose and including a front end:
• a nozzle coupled for fluid communication with the end portion of said hose and extending forwardly from the front end of said handgrip;
• a valve member operatively connected for movement with said nozzle and movable between open and closed positions so as to selectively allow and prevent liquid flow through said nozzle;
• and
• an actuating member including a manually operable lever coupled to said valve member at a coupling defining a pivot point located between said nozzle and said front end, said lever extending rearwardly over said handgrip and pivoting toward said handgrip for moving said valve member between said open and closed positions along a predetermined stroke length, said stroke length being limited by the coupling between said actuating member and said valve member.

A handgun and hose assembly for dispensing liquid, the assembly comprising:

• a hose including an end portion for conveying said liquid;
• a nozzle having an outlet and coupled for fluid communication with the end portion of said hose;
• a tubular member connected for fluid communication between said nozzle and the end portion of said hose;
• a valve seat positioned in said tubular member;
• an actuating member;
• and
• a plunger received by said tubular member and movable by said actuating member between open and closed positions with respect to said valve seat to selectively allow and prevent liquid flow through said nozzle outlet, said plunger being configured to increase the interior volume of said tubular member at a location downstream of said valve seat while moving into said closed position to thereby suck liquid back into said nozzle outlet.

A handgun and hose assembly for dispensing liquid, the assembly comprising:

• a hose including an end portion for conveying said liquid,
• a nozzle having an outlet and coupled for fluid communication with the end portion of said hose;
• a tubular member having a front end connected for fluid communication with said nozzle and a rear end connected for fluid communication with the end portion of said hose;
• a valve seat removably received by said tubular member;
• a plunger mounted for movement within said tubular member between open and closed positions;
• a sealing member positioned within said tubular member, said sealing member spaced away from said valve seat when said plunger is in the open position;
• and
• a first spring in said tubular member biasing said plunger in a direction away from said sealing member;
• a second spring in said tubular member biasing said sealing member against said valve seat when said plunger is in said closed position;
• an actuating member coupled to said plunger for moving said plunger between said open and closed positions;
• wherein said nozzle, plunger, valve seat and sealing member are each removable from the front end of said tubular member.
