Abstract
279,450. Walter, P. Oct. 19, 1926, [Convention date]. Steam traps in which a float-operated pilot valve controls the main discharge valve have a casing 1 provided with an inlet 2 and outlet 3, and a main discharge valve 8 controlling the discharge passage 6. A drum 7 containing the valve 8 is formed with a strainer 7, and a baffle, 4 is arranged in front of the steam inlet 2. An air vent 17 is controlled by a loose valve 30 having passages for the flow of air. A float 12 is guided on a central hollow shaft 31 carrying the valve 8 and piston 10, and formed at the top with a seating for the pilot valve 14. This valve is lifted by an extension 13 of the float engaging a plate 13a. When the device is put into operation, steam is gradually admitted while air escapes through the valve 30, this valve being ultimately closed by the steam pressure, which also keeps the valves 8 and 14 closed. The rising of the float opens the pilot valve which allows steam to pass down the tube 31 to the space below the piston 10 to lift the main valve 8. A screw 21 controls a bye-pass for regulating the rate of closing of the valve 8. The main valve can also be opened by hand through a screw 19, or by a rotary eccentric. A plunger 18 is provided for depressing the valve 30 for testing purposes. Modifications are described in which the valve 14 is not coaxial with the valve 8, but is operated by the float through a lever. In the Specification as open to inspection under Sect. 91 (3) (a) the bye-pass controlled by the screw 21 contains also a non-return ball valve (Fig. 5 Cancelled and not shown). This subjectmatter does not appear.in the Specification as accepted.
