Abstract
1517627 Tractor protection valves MIDLAND-ROSS CORP 15 June 1976 [14 July 1975] 24781/76 Headings F2F and F2V In a valve A with a port 68 communicable with a port 74 past a seat 70 and a bore 72 and having an elongated hollow member B with one open end communicable (via a diaphragm valve 58) with atmosphere and another open end 66, a flexible valve member C positioned between the seat 70 and the end 66 is operative when the pressure at the port 68 is higher than at the port 74 to communicate these ports while seating on and closing the open end 66 and alternatively when the pressure at the port 74 is higher than at the port 68 to close the seat 72 and vent the port 74 through the hollow member. The valve member C has a first flexible lip 88 extending radially and longitudinally of its body 80 engageable with the bore 72 and a second lip 86 engageable with a seating 89. The valve shown is a tractor protection valve wherein the hollow member B is a stepped piston which is urged to the right as shown, when the passage between ports 46 and 48 is pressurized by air from a tractor line 24 to release trailer parking or emergency brakes, to additionally connect a driver’s service brake valve through the ports 68 and 74 with trailer service brakes, the valve venting the trailer brakes through the piston B when the driver’s valve is released. In the absence of pressure air between the ports 46 and 48 a spring 62 moves the piston B leftwards to close the seats 66 and 70.
