摘要： This invention relates to breathing apparatus specially suited to submerged use, of the kind comprising a two-stage pressure reducer whose first stage is connected to the outlet valve of the diving cylinder and is responsible for the reduction from high pressure to medium pressure, while the second stage is associated directly with the mouthpiece and supplied it with air for respiration in response to each inhalatory suction from the user which exceeds a minimum threshold value termed the lifting suction.According to the invention, the first stage includes structure for adjusting the medium pressure, which has a member for direct manual operation which is mounted to be easily accessible and which can be operated by the user even when diving, so that the medium pressure can be adjusted whenever the lifting suction becomes too great, or whenever the effect of changes in the operation of the first stage is to alter it, or before diving in shallows.This first stage may comprise a throttling valve which is loaded by a spring, and the adjusting structure may include a screwed knob which acts on the members for adjusting the setting of the spring.

摘要翻译： 本发明涉及一种特别适合浸没式使用的呼吸器，其特征在于包括两级减压器，其一级连接到潜水缸的出口阀，负责从高压降至中压，而 响应于来自使用者的每次吸入吸力超过了称为提升吸力的最小阈值，第二阶段直接与吸口相关联并且向其提供空气用于呼吸。 根据本发明，第一级包括用于调节中压的结构，其具有用于直接手动操作的构件，其被安装为容易接近并且即使在潜水时也可由用户操作，使得中压可以 当提升吸力变得太大时，或者当第一阶段的操作变化的影响是改变它，或在浅水中潜水之前调整。 该第一阶段可以包括由弹簧加载的节流阀，并且调节结构可以包括螺纹旋钮，其作用在构件上用于调节弹簧的设置。
