Abstract
A fluid flow regulator having a spring clip frictionally engaging the pivoting regulator lever to stabilize flow fluctuations. Alternatively, a disk wedge with opposite leg portions frictionally engages the moving regulator diaphragm.
Claims4
In a gas pressure regulator including a gas flow control orifice communicating the gas from a regulator input to a regulator output, a moving diaphragm responding to pressure changes, and a pivoting lever coupled between the diaphragm and the flow control orifice to regulate the flow of gas through the flow control orifice in response to the moving diaphragm, the improvement of a stabilizer for fluid flow fluctuations to stabilize pressure regulation, said stabilizer comprising:
- a spring clip mounted in said gas pressure regulator in frictional engagement with said pivoting lever, said spring clip including opposite parallel surfaces frictionally engaging said pivoting lever during pivoting movement of said pivoting lever.
In a gas pressure regulator including a gas flow control orifice communicating the gas from a regulator input to a regulator output, a moving diaphragm responding to pressure changes, and a pivoting lever coupled between the diaphragm and the flow control orifice to regulate the flow of gas through the flow control orifice in response to the moving diaphragm, the improvement of a stabilizer for fluid flow fluctuations to stabilize pressure regulation, said stabilizer comprising:
- a disk wedge having opposite leg portions, said disk wedge mounted in said gas pressure regulator in frictional engagement with said moving diaphragm.
In a gas pressure regulator including a regulator body having a fluid inlet and a fluid outlet, a gas flow control orifice communicating the gas from the fluid inlet to the fluid outlet, a moving diaphragm responding to pressure changes, and a pivoting lever pivotally mounted to the regulator body and coupled between the diaphragm and the flow control orifice to pivotally move and regulate the flow of gas through the flow control orifice in response to the moving diaphragm, the improvement of a stabilizer for fluid flow fluctuations to stabilize pressure regulation, said stabilizer comprising:
- a spring member mounted in said gas pressure regulator in frictional engagement with said pivoting lever;
- said spring member including a base portion and a surface portion extending from said base portion;
- said base portion mounted to said regulator body, and said surface portion in frictional engagement contact with said pivoting lever during said pivotal movement to frictionally resist and dampen said pivotal movement and thereby stabilize pressure regulation.
