Abstract: A valve assembly has a housing and a poppet-carrying portion. The housing includes an inlet port, an outlet port, an opening, and a assembly portion including helical grooves. The poppet-carrying portion is configured to be inserted through the opening and engage with the assembly portion. The poppet-carrying portion comprises a poppet head, a closure including protruding arms, convolutions, and a stopping portion. The convolutions extend between the poppet head and the closure and provide compliance such that the poppet head is movable relative to the closure. The stopping portion extends from the closure toward the poppet head and is spaced apart from the poppet head by a maximum compression distance. At a first fluid pressure, the protruding arms engage with the helical grooves, and the poppet head is positioned in a pre-load position that prevents the fluid from discharging through the outlet port.
