Abstract
391,663. Pressure-regulating valves. KROMSCHRODER, F., 33, Bergstrasse, Osnabr³ck, Germany. Aug. 22, 1932, No. 23506. [Class 135.] In a pressure regulator of the kind described in Specification 5093/08, [Class 135, Valves &c.], in which the end of a conduit connecting a closed chamber 9, as shown in the Figure beneath the regulating membrane 7 with a lateral enlargement of the outlet chamber 2 is subject to suction action, so that an increased gas pressure results in an increased flow, the valve plate 3 and the walls of the outlet chamber are formed so that the flow of gas over the end of the connecting conduit 8 is substantially free from eddies. In one form of the invention the conduit 8 itself terminates in the enlargement of the chamber 2 and has a nozzle of trumpet or cylindrical form positioned so as to be approximately parallel to the path of flow. In another form, the conduit 8 terminates in an annular recess in the walls of the chamber 2, the edge of the recess nearer the valve plate 3 projecting farther into the chamber 2 than the other edge so as to augment the suction action. This recess may extend only partly round the chamber 2. In a third form, shown particularly in the Figure, the conduit 8 ends in a bore 20 penetrating the valve body and provided with a nozzle 21 having a throughpassage and a slot 22 arranged obliquely thereto. The rear end of the nozzle 21 has a positioning slot 24 parallel to or at right-angles to the slot 22 and the abutment face 25 is at a known distance from the valve spindle so that the nozzle 21 may be accurately positioned. The eddy-free passage of the gas is assisted by arranging that the distance of the valve pla e 3 from its seat 4 is greater on the side adjacent the nozzle 21, equally eccentrically arranged eyes 27, 28 on the plate 3 and spindle 5 serving this purpose. The plate 3 and spindle 5 are coaxial when the former is closed. In all the constructions the usual equalization membrane 6 is provided and is connected to the spindle 5. There is a venting nozzle 12 for the chamber 11. Alternative to the nozzle 12, a device which closes the connection between the chamber 11 and the atmosphere if the membrane 7 should leak, may be used. Several conduits 8 may be arranged between the chambers 9, 2.
