Abstract
A back plate for a breathing apparatus comprises a back plate frame for supporting a cylinder of breathable gas; and a pressure reduction valve configured to receive breathing gas from a cylinder of breathable gas; and a resiliently deformable element configured to support the pressure reduction valve on the back plate frame so as to permit relative movement between the pressure reduction valve and the back plate frame.
Claims20
A back plate for a breathing apparatus, the back plate comprising:
- a back plate frame for supporting a cylinder of breathable gas;
- a pressure reduction valve configured to receive breathing gas from the cylinder of breathable gas supported by the back plate frame;
- and
- a resiliently deformable element configured to support the pressure reduction valve on the back plate frame so as to permit relative movement between the pressure reduction valve and the back plate frame,
- wherein the pressure reduction valve comprises a cylinder connection configured to pneumatically connect the pressure reduction valve and the cylinder of breathable gas, and wherein the resiliently deformable element comprises an opening configured to at least partially accommodate the cylinder connection.
