摘要： A gas-blast switch or circuit-interrupter contains a fixed set of contacts and a movable set of contacts. Each contact set possesses an arc contact and a rated current contact coaxially surrounding the related arc contact. Operatively associated and co-movable with the movable contact set is a blast nozzle which surrounds the arc contact of such movable contact set. In the cut-on position the blast nozzle is closed by the fixed arc contact and is operatively connected with a pressure chamber which can be pressurized during a cut-off stroke. At the outflow end of at least one of the arc contacts there are arranged means in order to axially and outwardly deflect the switching gas flowing-out of such end during the cut-off stroke. The deflecting means comprise deflection hoods of essentially cup-shaped configuration which are open at their ends confronting one another and possess a base or floor portion containing a half toroidally shaped deflection surface at the peripheral edge of which there merges an essentially cylindrical portion or section. Each such cylindrical portion carries a plurality of tongues which protrude inwardly from its inner wall and which are arranged at a substantially uniform circumferential spacing from one another.

摘要： A movable contact element is surrounded by a co-movable blast nozzle which in the cut-on position is closed by a stationary contact element which is in engagement with the movable contact element. At its inlet side the blast nozzle is flow connected with a pump chamber or compartment which can be pressurized during the cut-off stroke. This pump chamber is constructed in a jacket or shell chamber-like fashion and bounded by an inner cylinder and an outer cylinder. The inner cylinder carries the movable contact element and the outer cylinder carries the blast nozzle. Both cylinders are displaceable by means of a stationarily supported pump piston. In order to prevent any obstruction to the flow of the extinguishing gas which is effluxing out of the pump chamber during the cut-off stroke, both of the cylinders are solely connected with one another at their ends facing away from the blast nozzle by means of a substantially ring-shaped floor member which is preferably formed at both cylinders. In the floor member there are provided at least two guide bores equipped with sliding or wiper contacts. Engaging through the guide bores is a respective electrically conductive, stationarily anchored column member supporting the pump piston.
