Abstract: 1364818 Brake valves SCOVILL MFG CO 13 Feb 1973 7036/73 Headings F2F and F2V In a relay valve assembly particularly for a tractor-trailer braking system admission of pressure to an inlet control chamber 76 causes downward movement of diaphragm 20 and consequently of a valve member 48, a gasket 52 being unseated at 34 thereby allowing air pressure from a source to pass to brake cylinders via inlet 22 and an outlet 26, Fig. 1 (not shown), until the pressure acting on the underside of the diaphragm equalizes that in control chamber 76, the diaphragm then being raised to permit gasket 52 to seat once again. Reduction of pressure in chamber 76 for brake release causes diaphragm 20 to flex upwardly due to the higher air pressure acting on the underside thereof, whereby a seat 65 is raised from a gasket 64 to vent this air pressure via an exhaust tube 66, around which the diaphragm is sealingly retained, and exhaust openings 70. Control chamber 76 communicates with a solenoid valve (82) of the assembly controlled by a skid sensing computer which valve first cuts off control pressure to the chamber 76 and thereafter vents the control chamber to allow diaphragm 20 to flex upwardly and vent the brake cylinder pressure when skidding is detected. Valve member 48 has a circular axial bore 50 in which is located a polygonal, preferably hexagonal shaft 46 on which the valve member slides, a closed chamber 56 being kept in communication with exhaust through the tube 66 and the axial bore allowing equalizaton of pressure on the valve member within the inside diameter of the wall of a flange 40 in which flange 54 of the valve member 48 is slidably located.

The spindle 6 is furnished with a pin 7 engaging a groove 5 having a vertical upper portion and a helical lower portion, and is connected through a. rod 17 with a dished mould bottom 20. The mould 2 is vented at 22. The pitch of the groove 5 differs from that of the helical blades to cause relative rotary movement of the lid 15 as the head is brought into operation. Fig. 5 shows a modification involving a hinged lid 15 operable synchronously with the head through a rod 25 and lever 24 and actuating the mould bottom through a link 27 and lever 28; the mould bottom is rotated through a rack 30. In a further modification, a hinged lid is furnished with a central rotary portion. The helical ribs on the head taper towards their roots, and to cut wider grooves in the material the pitch of the ribs may be varied.
