Abstract: The invention relates to a valve for diving equipment which comprises a valve housing having a charging port, a bottle port and an outlet port. Reducing valve means and reserve valve means are provided in series in the main fluid flow path. The reserve valve means remains open until a pressure on the downstream side thereof has dropped to a point where air in the bottle is at a predetermined low pressure, at which time the reserve valve closes. The reserve valve has means associated therewith which are manually operable to open the reserve valve to allow the remaining contents of the bottle to be fully utilized.

Abstract: The invention relates to a valve assembly for diving equipment having an air inlet to which a container bottle containing pressurized air may be attached and an air outlet to which the breathing equipment is attachable. Between the air inlet and air outlet is reserve valve means which is biased in an opening direction by pressurized air on the downstream said thereof and in a closing direction by valve actuator means which operates to close the reducing valve when the air pressure on the downstream side drops to a predetermined minimum pressure. First and second guide means are provided for the valve actuator means which actuator means has a range of movement relative to each of said guide means with said movement being automatic relative to the first guide means and manually controllable relative to the second guide means, The valve actuator means is transferable from the first guide means to the second guide means only at a point corresponding substantially to said minimum pressure.

Abstract translation: 本发明涉及一种用于潜水设备的阀组件，其具有可以附接有加压空气的容器瓶的空气入口和可附接呼吸设备的空气出口。 在进气口和出气口之间是备用阀装置，其通过加压空气在其下游被加压空气偏压并且在关闭方向上被阀致动器装置驱动，该致动器装置用于在下游侧的空气压力时闭合减压阀 下降到预定的最小压力。 第一和第二引导装置设置用于阀致动器装置，该致动器装置相对于每个所述引导装置具有一定范围的运动，所述运动相对于第一引导装置是自动的，并相对于第二引导装置可手动控制。 致动器装置只能在基本上对应于所述最小压力的点处从第一引导装置传递到第二引导装置。
