PRESSURE REGULATING DEVICE |
摘要 |
The pressure regulating device (10) is adapted to be interposed between a pressurized fluid supply and a fluid receiving space into which the pressurized fluid is discharged at a regulated reduced pressure. The device (10) comprising a housing (12) and a diaphragm assembly (30), wherein said housing (12) comprises a means for coupling to said pressurized fluid supply in a sealed manner, and a diaphragm chamber (18) adapted to communicate with said fluid receiving space through a fluid discharging passage (23) and being separated from said pressurized fluid supply by a barrier wall (26) having a central port (28) extending therethrough, wherein said diaphragm assembly (30) comprises a elastic diaphragm (31) connected to a throttle head (34) by a stem (32), said stem (32) extending through said central port (28) to define a flow passage therein, and said diaphragm (31) being secured along its periphery to said housing (12) so that in its initial position, the diaphragm (31) rests on a planar upper surface of said barrier wall (26), and wherein said housing (12) is made of a rigid gas-tight plastic material, and wherein said diaphragm (31), said stem (32) and said throttle head (34) are integrated into one piece as a diaphragm assembly, said integrated piece being made of a gas-tight elastomeric material. |

1. A pressure regulating device (10) adapted to be interposed between a pressurized fluid supply and a fluid receiving space into which the pressurized fluid is discharged at a regulated reduced pressure, said device comprising
a housing (12) having
a means for coupling to a pressurized fluid supply in a sealed manner, anda diaphragm chamber (18) adapted to communicate with a fluid receiving space through a fluid discharging passage (23) and being separated from said pressurized fluid supply by a barrier wall (26) having a central port (28) extending therethrough, and a diaphragm assembly (30) having
an elastic diaphragm (31) connected to a throttle head (34) by a stem (32),said stem (32) extending through said central port (28) to define a flow passage therein, andsaid diaphragm (31) being secured along its periphery to said housing (12) so that in its initial position, the diaphragm (31) rests on a planar upper surface of said barrier wall (26), wherein said housing (12) is made of a rigid gas-tight plastic material, and wherein said diaphragm (31), said stem (32) and said throttle head (24) are integrated into one piece as a diaphragm assembly (30), said integrated piece being made of a gas-tight elastomeric material. |
