Abstract
A gas generator comprises a housing and a propellant contained in the housing, the propellant, after activation, releases a fluid which is under pressure, and the housing has a first and a second housing part, which are movable relative to each other under pressure and form an overflow opening with a variable flow area depending on the pressure in the housing. Either the first or the second housing part, or both, have spacing means, the spacing means are designed so that in the case of the relative movement of the housing parts with respect to each other, a minimum value of the variable flow area is maintained.
Claims21
A gas generator (10) comprising
- a housing (20) and a propellant contained in the housing,
- the propellant, after activation, releasing a fluid which is under pressure,
- and the housing (20) having a first (22) and a second housing part (24), which are movable relative to each other under pressure and form an overflow opening (46) with a variable flow area depending on the pressure in the housing,
- characterized in that either the first (22) or the second housing part (24), or both, have spacing means (44, 48, 50), the spacing means (44, 48, 50) being designed so that in the case of the relative movement of the housing parts (22, 24) with respect to each other, a minimum value of the variable flow area is maintained.
A gas generator (10) comprising
- a housing (20) and propellant contained in the housing,
- wherein the propellant, after activation, releases a fluid which is under pressure,
- and wherein the housing (20) has a first (22) and a second housing part (24), which are moveable relative to each other under pressure and form an overflow opening with a variable flow area depending on said pressure in said housing,
- characterized in that between the first (22) and the second housing part (24), spacing means (52, 56, 60) are arranged, the spacing means (52, 56, 60) being separate from the first (22) and second housing part (24) and designed so that in the case of said relative movement of said first and second housing parts (22, 24) with respect to each other, a minimum value of the variable flow area is maintained.
