Abstract
A pressure regulator includes a hermetically sealed housing that limits the potential for leak paths to atmosphere or exterior to the housing. The regulator includes a dampening arrangement for limiting oscillations during high flow rates. A stem clip secures a poppet assembly to a movable member of the regulator. The stem clip permits radial movement of the poppet assembly to facilitate centering of the poppet assembly relative to a valve seat. The poppet assembly includes a self-tapping poppet to precisely set the opening between the poppet and valve seat irrespective of tolerance stackup.
Claims25
A pressure regulator comprising:
- a housing having a chamber defined therein;
- an inlet and outlet operatively communicating with said chamber;
- means for selectively regulating fluid flow between said inlet and outlet, said regulating means including a movable pressure responsive member having a first portion secured in the chamber, and a second portion associated therewith and adapted for movement relative to the first portion, the first and second portions forming a closed cavity entirely defined in the chamber having a predetermined pressure charge therein that establishes the opening and closing pressure value of the regulator, the regulating means further including a resilient member disposed between the first and second portions for dampening movement of said regulating means to limit oscillations thereof under selected conditions.
A pressure regulator comprising:
- a housing having a chamber defined therein;
- an inlet and outlet operatively communicating with said chamber;
- means for selectively regulating fluid flow between said inlet and outlet, said regulating means including a closed cavity defined in the chamber and being substantially entirely enclosed by fluid as the fluid passes from the inlet to the outlet, the closed cavity having a predetermined pressure charge therein that establishes the opening and closing pressure value of the regulator, the regulating means further including a poppet assembly that opens and closes one of said inlet and outlet;
- and
- means for connecting said poppet assembly to said regulating means, said connecting means permitting selective movement therebetween.

A pressure regulator comprising:
- a housing having a chamber defined therein;
- an inlet and outlet operatively communicating with said chamber;
- means for selectively regulating fluid flow between said inlet and outlet, said regulating means including means for dampening movement of said regulating means to limit oscillations thereof under selected conditions;
- and
- a poppet assembly operatively associated with the regulating means adapted for selective engagement with a valve seat defined between said inlet and outlet, said poppet assembly includes means for centering the poppet assembly relative to the valve seat, the centering means including a stem having a poppet received on one end and an enlarged base portion defined at the other end, said stem being retained on said second portion by a clip having an opening substantially larger than a transverse dimension of said stem to permit transverse movement of said stem relative thereto.
2 more elements
A pressure regulator comprising:
- a housing having a chamber defined therein;
- an inlet and outlet operatively communicating with said chamber;
- means for selectively regulating fluid flow between said inlet and outlet, said regulating means including a poppet assembly that opens and closes one of said inlet and outlet;
- means for connecting said poppet assembly to said regulating means, said connecting means permitting selective movement therebetween;
- and
- means for limiting rotational movement between said resilient means and said poppet assembly, said rotational limiting means being defined by a generally rectangular end on said poppet assembly received in a generally rectangular cavity in said connecting means.
3 more elements
A pressure regulator comprising:
- a housing having a chamber defined therein;
- an inlet and outlet operatively communicating with said chamber;
- means for selectively regulating fluid flow between said inlet and outlet, said regulating means including a closed cavity defined in the chamber having a predetermined pressure charge therein that establishes the opening and closing pressure value of the regulator, the regulating means further including a movable pressure responsive member having a first portion secured in the chamber, a second portion associated therewith and adapted for movement relative to the first portion, and a bellows interposed between the first and second portions having an outer peripheral portion closely received in the bellows to provide support therefor under high pressure conditions, and means for dampening movement of said regulating means to limit oscillations thereof under selected conditions.
