Abstract
Example embodiments relate to a gas-pressure regulator having an inlet, an outlet, a housing, a diaphragm, a control element, a control chamber and a discharge chamber. The inlet and the outlet each open onto the control chamber, wherein the diaphragm partially delimits the control chamber. The diaphragm and the control element are movable relative to each other, wherein a passage between the control chamber and the discharge chamber is open in a relative discharge arrangement of the diaphragm and the control element. An adjustable biasing element impedes a relative movement between the diaphragm and the control element.
Claims3
A gas-pressure regulator, comprising:
- an inlet, an outlet, a housing, a diaphragm, a control element, a control chamber, a discharge chamber, an adjustable biasing element and a spring component,
- wherein the inlet and the outlet each open onto the control chamber,
- wherein the diaphragm partially delimits the control chamber,
- wherein the diaphragm and the control element are configured and arranged within the housing such that the diaphragm and the control element are movable relative to each other,
- wherein a passage between the control chamber and the discharge chamber is open in a relative discharge arrangement of the diaphragm and the control element,
- wherein the adjustable biasing element impedes a relative movement between the diaphragm and the control element, wherein the relative movement between the diaphragm and the control element takes place against a spring force of the spring component,
- wherein the adjustable biasing element acts on the spring force,
- wherein the adjustable biasing element is configured and arranged so as to be movable relative to the control element,
- wherein a closing force of the spring component depends on a position of the adjustable biasing element relative to the control element,
- wherein the adjustable biasing element can assume one of two fixed positions and is movable between the two fixed positions,
- wherein the adjustable biasing element prevents the discharge arrangement from being reached, and
- wherein an eccentric component having an offset axis of rotation is provided, by which the eccentric component causes an axial movement of the adjustable biasing element along the control element, or
- wherein, in an inactive state, a protrusion of the control element rests in a recess of the adjustable biasing element and, by a rotation of the adjustable biasing element about a longitudinal axis of the control element, the protrusion is located outside the recess so that the adjustable biasing element assumes a deeper axial position in a direction of the diaphragm.
