Pressure actuated valve assembly

A valve assembly for use in a high pressure fluid flow system, comprising:

• a body defining a first longitudinal axis, said body having a substantially cylindrical bore passing therethrough, said body further including an inlet opening and an outlet opening, said inlet opening and said outlet opening being in communication with said bore;
• a valve disposed within said bore and being selectively movable to a closed position and an open position;
• a control lever fixedly attached to said valve, said control lever being operable to displace said valve between the closed position and the open position;
• a transfer-hose having a proximal end having a first coupling attached thereto, and a distal end having a second coupling attached thereto, said first coupling being attachable to said body adjacent said outlet opening;
• and
• a linkage extending from said lever to said second coupling, said linkage being operable in response to a displacement of said second coupling, said second coupling being displaceable to stress said linkage to define a second longitudinal axis, the second longitudinal axis being displaceable between a first position and second position, the first position of said second longitudinal axis being divergent relative to the first longitudinal axis and the second position of the second longitudinal axis being convergent relative to the first longitudinal axis.

A valve assembly for use in a high pressure fluid flow system, comprising:

• a body defining a first longitudinal axis, said body having a substantially cylindrical bore passing therethrough, said body further including an inlet opening and an outlet opening opposite said inlet opening, said inlet opening and said outlet opening being in communication with said bore, said body further having means for coupling said body to a source of high pressure fluid;
• a valve disposed within said bore, said valve selectively movable to a closed position and an open position;
• a control lever fixedly attached to said valve, said control lever being operable to displace said valve between the closed position and the open position;
• a transfer-hose having a proximal end having a first coupling attached thereto, and a distal end having a second coupling attached thereto, said first coupling being attachable to said body adjacent said outlet opening, said transfer-hose being structured and configured to conduct high pressure fluid flow therethrough, said transfer-hose further including a flexible tubular member, said flexible tubular member being displaceable to displace said second coupling between the first and second positions in response to the high pressure fluid flow within said flexible tubular member, said transfer-hose further being structured and configured to be limp in absence of high pressure fluid flow in said transfer-hose and to be distended in response to the high pressure fluid flow in said transfer-hose;
• a linkage extending from said lever to said second coupling, said linkage being operable in response to a displacement of said second coupling, said second coupling being displaceable to stress said linkage to define a second longitudinal axis, the second longitudinal axis being displaceable between a first position and second position, the first position of said second longitudinal axis being divergent relative to the first longitudinal axis and the second position of the second longitudinal axis being convergent relative to the first longitudinal axis, said linkage being structured and configured to be flexible and resist stress deformation and being a predetermined length to displace said lever a predetermined amount in response to a predetermined displacement of said second coupling.
