Abstract
A securing device for a valve of a pressurized gas tank of a respiratory protection device, characterized by a securing element, which can be moved from a closed position to a flow position, especially an open position, by applying a torque, wherein at least one part of a housing serves as an abutment for the securing element when the torque is applied, wherein the valve is closed in the closed position of the securing element and can be brought spontaneously into a flow position after applying a particular torque to the securing element.
Claims19
A securing device for a valve of a pressurized gas tank, comprising:
- a securing element that comprises at least a portion received in a recess defined by a movable valve element of the valve, wherein the securing element is moved from a closed position to a flow position by applying a torque, wherein at least one part of a housing comprises an abutment for the securing element when the torque is applied, wherein the abutment is arranged at least partly on a sliding block guide in the housing, wherein the valve is closed in the closed position of the securing element and is brought spontaneously into a flow position, in which the securing element is displaced out of contact with the movable valve element, after applying a specified torque to the securing element.
A securing device for a valve of a pressurized fluid tank, comprising:
- a valve connected to the pressurized fluid tank;
- a movable valve element disposed within the valve and reversibly obstructing flow of fluid from the pressurized fluid tank via the valve;
- and
- a securing element that, in a first position, comprises at least a portion received within a recess defined by the movable valve element and holds the movable valve element in a closed position;
- the securing element movable to a second position by lever action about a fulcrum provided by at least one element of the valve;
- wherein, in the second position, the securing element is displaced out of contact with the movable valve element to allow the movable valve element to spontaneously transition to an open position to provide flow of the fluid from the pressurized fluid tank.
A pressurized fluid tank, comprising:
- a tank holding pressurized fluid;
- a valve connected to the tank;
- a movable valve element disposed within the valve and reversibly obstructing flow of fluid from the tank via the valve;
- and
- a securing element that, in a first position, comprises at least a portion received within a recess defined by the movable valve element in a fashion to hold the movable valve element in a closed position;
- the securing element being movable to a second position by lever action about a fulcrum provided by at least one element of the valve;
- wherein, in the second position, the securing element is displaced out of contact with the movable valve element to allow the movable valve element to spontaneously transition to an open position to provide flow of the fluid from the tank.
