Abstract:
1. A secondary resetting shut-off valve assembly, said assembly comprising: a housing having an inlet and an outlet, a valve mechanism disposed in a fluid communicating relation with said inlet and said outlet, a flow measurement mechanism comprising a measurement member disposed in an operative engagement with said valve mechanism, a reduction apparatus to at least partially translate an amount of movement of a detection member, said reduction apparatus comprises a series of reduction members mounted in a fixed array about a plurality of reduction member shafts, said reduction members comprise a series of gear members having interlocking teeth such that movement of one of said reduction members causes an entire array of said reduction members to move correspondingly, said flow measurement mechanism structured to measure a predetermined amount of said fluid flow through said housing, said measurement member disposed in an initial orientation prior to said fluid flow through said housing, said measurement member structured to move from said initial orientation during said fluid flow through said housing, said measurement member structured to move back to said initial orientation when said fluid flow through said housing terminates before said predetermined amount of said fluid flow through said housing is measured, said measurement member is further structured to rotate during said fluid flow through said housing, said measurement member comprises a receiver, said receiver structured to rotate along a path of rotation with said measurement member during said fluid flow through said housing, said valve mechanism structured to be disposed into a closed configuration to prevent said fluid flow through said housing after said predetermined amount of said fluid flow through said housing is measured, and said valve mechanism comprises a valve plunger having a distal end comprising a tip, said tip being normally disposed in an abutting relation to a portion of said measurement member along said path of rotation of said receiver.
