Abstract

1293600 Valves MITA MACCHINE INFILZATRICI TABACCO AUTOMATICHE SARL 27 Nov 1969 58078/69 Heading F2V A valve has a supply port 9 applying pressure to a differential piston 24 through passages 14 and 10, 11, 12, 22 to hold an exhaust valve 16 closed until a pilot valve 21 is moved to the left to connect the passage 22 to an exhaust port 27 and allow the exhaust valve 16 to open and is then further moved to the left to lift a spring-loaded ball valve 13 to allow fluid from a consuming apparatus to flow through a port 19 to exhaust. The rate of exhaust flow is limited by a further ball valve 18 held away from its seat by an adjustable pin 20. A slidable member 1 operates the pilot valve which allows supply fluid to flow under pressure through the spring-loaded ball valve 32 into the consuming apparatus when it is in the position shown. A lever 37 enables the position of the valve 32 and hence the travel of the member 1 necessary to open the valve to be adjusted. The apparatus may be used to control a lifting device on an agricultural tractor.
