Claims11
In a water blasting gun having a block, said block having a high pressure fluid inlet, a high pressure fluid outlet, first passageway means between said high pressure inlet and outlet, a low pressure fluid outlet, second passageway means between said first passageway means and said low pressure outlet, and means for controlling fluid communication between said high pressure fluid inlet and said low pressure fluid outlet, the improvement comprising:
- said controlling means including;
- valve seat means and valve means positioned in said block, said valve means being biased toward a first position out of engagement with said valve seat means, and valve activating means, engageable with said valve means, for urging said valve means into engagement with said valve seat means, said valve seat means includes a depending cage portion which carries a valve encompassing spring member and slidably receives a valve portion therein;
- and
- said block includes bore means for slidably receiving and guiding a stem portion of said valve means.
In a water blasting gun having a block, said block having a high pressure fluid inlet, a high pressure fluid outlet, first passageway means between said high pressure inlet and outlet, a low pressure fluid outlet, second passageway means between said first passageway means and said low pressure outlet, and means for controlling fluid communication between said high pressure fluid inlet and said low pressure fluid outlet, the improvement comprising:
- said controlling means including:
- valve seat means and valve means positioned in said block, said valve means being biased toward a first position out of engagement with said valve seat means, and valve activating means, engageable with said valve means, for urging said valve means into engagement with said valve seat means;
- and
- said valve seat means includes a depending cage portion which carries a valve encompassing spring member and slidably receives a valve portion therein.
Quick release mechanism for use in a water blast gun, said mechanism comprising:
- fluid dump means adapted to removably engage a gun block;
- means for controlling fluid passage, through said gun block, said control means including a valve seat housing and valve means;
- means for releasably engaging said dump means and said control means;
- and
- wherein said fluid dump means' gun engagement means includes threaded tubular means removably engageable with said block, and said control means engaging means comprises a first passageway in a tubular wall of said tubular means and a second passageway angularly communicating with said first passageway.
