A mixing valve for mixing hot and cold fluids comprises a valve body having its interior divided into two compartments 10, 11 by a diaphragm 14 extending across the interior of the body, inlets 15 and 16 for the hot and cold fluids respectively opening into compartment 11, the hot fluid inlet 15 being controlled by a valve member 23 which is connected to a transfer member in the form of a cylindrical plug made in two parts 30, 31 secured together by a central screw 32 so as to clamp between the two parts 30 and 31 the central portion of the diaphragm 14, the transfer member having four small-bore passages 33 extending therethrough to provide communication between the two compartments, a coiled compression spring 48 located within a hollow spindle 41 and by means of a pad 49 loading the diaphragm in a valve closing direction, a bi-metal coil assembly 42 consisting of two coils connected in series, one end being fixed to a boss 40 and the other end connected to a sleeve 43 fixed to the spindle 41, an outlet 50 for the fluid mixture from the compartment 10 and a rotary disc valve member 34 having four ports 44 extending therethrough which co-operate with the ports 33 in the transfer member to control the flow of mixed fluid through the valve. The valve member 34 is secured to the underside of a plate 36 having diametricallyopposed upstanding lugs 37 each of which is slotted to engage lugs 38 on the underside of a plate 39 formed integrally with the boss 40 mounted freely upon the spindle 41. The bimetal coil assembly is disposed in the path of the fluid mixture passing to the outlet 50 and any variation in temperature results in movement of the bi-metal coil assembly in the appropriate direction to vary the rotary valve member 34 relative to the transfer member, thus varying he differential pressure across the diaphragm 14 and giving an appropriate movement of the hot fluid control valve member 23 to increase or decrease the flow of hot fluid. The initial temperature setting of the bi-metal coil assembly is adjusted by rotating the spindle 41. Adjustment may also be provided for setting the initial loading of the spring 48. A diffuser member 24 prevents the hot fluid impinging directly on the diaphragm 14. A piston may be substituted for the diaphragm.

Abstract: 180,418. Vacuum Brake Co., Ltd., and Walker, W. P. Feb. 21, 1921. Fluid-pressure braking-apparatus of the kind in which a supplementary cylinder becomes operative only when the pressure in the primary cylinder reaches a predetermined value comprises an upper supplementary vacuum cylinder b coxial with the primary cylinder a and provided with a number of links h carrying rollers h<1> in inclined slots and wedges h<2> which engage the rollers. The piston c of the lower cylinder has attached thereto racks k adapted for engagement with the rollers h<1>. Communication of the lower chamber of the upper cylinder b with that cf the lower cylinder is controlled by a spring pressed valve l and a ball valve n<1>. Under running conditions, the vacuum is maintained in the upper cylinder by way of the passage n the ball valve n<1> and the passage g. When air is first admitted to the lower chamber of the cylinder a the piston thereof is operated in the usual manner but the piston d is unaffected as the ball valve n<1> prevents air from being supplied to the cylinder b and the coupling- members k, h are disengaged. When as for instance in the case of a loaded wagon a greater braking pressure is required, the admission of air to the cylinder a is continued until it is sufficient to lift the valve l, thus by-passing the ball valve n<1> and thereby admitting air beneath the upper piston d. As soon as this piston lifts the air is enabled to pass beneath it also by way of the upper part of the passage g which was previously closed at the seating m. Further the movement of the links h causes the wedges h<2> to force the rollers h<1> into engagement with the racks k so that the pistons become coupled together.
