Definitions
- the invention relates to a compressed gas cylinder with a coupling for connection to a to a consumer, a distributor or a filling station, respectivelysch widerbaren connecting member, in particular for SCBA.
- the associated compressed air cylinders in the area of the cylinder valve have a connection piece, which is usually arranged perpendicular to the longitudinal axis of the compressed air cylinder, with an internal thread.
- the design of the compressed air cylinders with such a connection piece is determined by standardization and not changeable.
- the connection of the compressed air cylinder for example, with a pressure reducer or a manifold of a SCBA, so far causes difficulties, as the connecting piece of the bottle or rotatable by handwheel male thread fitting on pressure reducer or manifold when creating the heavy filled bottle, especially during rapid bottle change during an insert, can easily tilt. The time required anyway for the production of the screw connection is thereby even greater.
- the invention is based on the object, starting from the standardized internal thread connection of the compressed gas cylinder to develop a coupling for the simple, fast and secure connection of the compressed gas cylinder to a consumer and for their safe handling in a decoupled state, even under difficult operating conditions.
- the object is achieved with a trained according to the features of claim 1 injection gas cylinder.
- the basic idea of the invention consists in the arrangement of a closure ring held in a decoupled state in an annular gap between a closing mushroom and a closing ring so that a limited gas volume flow can flow out when the compressed gas cylinder is open.
- the coupling comprises the arrangement of a separate, between the compressed gas cylinder and, for example, the pressure reducer of a compressed air breathing device connected coupling part, which is screwed to the standardized connection of the compressed gas cylinder and can be connected via connector means in a simple manner and quickly and safely to the pressure reducer exemplified here.
- a coupling is extremely advantageous because the connection is made only by nesting two plug-in elements.
- the connector is designed so that each spring-loaded closure elements are arranged on the open sides of the two connecting elements, which cover the connection side in the non-coupled state and thus prevent contamination and allow anytime secure coupling process.
- the closure elements are axially displaced during mating by the respective other connector means to release the gas passage.
- the closure element acts on the coupling part connected to the compressed gas cylinder at the same time as a discharge, in such a way that accidentally opening the cylinder valve in the uncoupled state, a small compressed air volume flow flows through the spring-loaded closure element and thus accidents due to the gas suddenly emerging at high speed can be prevented.
- locking means for locking the connector are also provided on the mutual plug-in elements, wherein the latching can be solved only by a manually executed rotational and longitudinal movement of an actuator provided on the coupling part and thus an automatic release of the connector is excluded. Due to the design as a plug connection in combination with the locking and locking elements, the coupling according to the invention satisfies the demands placed on such a connection for a high level of safety and rapid production of the connection.
- a compressed air cylinder 2 in the usual way with a connecting piece 3 with internal thread 4 is provided.
- a plug-in nipple 8 In a threaded bore 5 of the pressure reducer 6 is formed with a plug-in nipple 8 connecting member 7 is screwed.
- the plug-in nipple 8 has a standing under the action of a helical compression spring 9 cap 10 which protects in conjunction with a seal 11, the pressure reducer 6 in the not connected to the compressed air cylinder 2 state from contamination.
- the coupling part 12, with which the connection between the connecting piece 3 and the plug-in nipple 8 is produced, comprises a threaded sleeve 13, which is screwed into the connecting piece 3 by means of a handwheel 14.
- the sealing in the connection piece takes place by means of a seal 15.
- the coupling part 12 has a closing mushroom 17 which is formed in the air passage bore 16 and forms an annular gap 19 with a closing ring 18.
- the annular gap 19 is closed by a locking ring 21 which is under the action of a helical compression spring 20 and thus reduces the risk of contamination.
- This spring-loaded locking ring 21 forms together with the closing mushroom 17 but at the same time a discharge protection, which limits the amount of outflowing gas to about 5 l / min in uncoupled state inadvertent opening of the cylinder valve 1 and thereby limits the risk of accidents and which also allows that the coupling part 12th optionally can be separated from the pressurized compressed air cylinder 2.
- Fig. 4 shows the coupling part 12 and the plug nipple 8 in coupled - nested - state.
- Verrastkugeln 23 Only by two successive activities of the user, namely turning the movably mounted handwheel 14 and then pulling the handwheel 14 against a mounted on the coupling member 12 helical compression spring 24, the Verrastkugeln 23 are released to pull off the coupling part 12 of the connected to the pressure reducer 6 nipple 8 to be able to.
- the small and handy coupling part 12 can be easily, quickly and safely connected to the compressed air cylinder 2 and remain at this.
- the connection of the provided with the coupling part 12 compressed air cylinder 2 to the pressure reducer 6, a distributor element or the like., Which are formed with a corresponding plug-in nipple 8, is very simple and requires no time.
- corresponding chamfers may be formed on both parts.
- the nipple may also be connected to the compressed air cylinder while the coupling part is attached to the pressure reducer.
