A control valve comprises a housing having an inlet and an outlet with a valve seat 11 therebetween, a closure member 12 between the inlet and outlet, a chamber 3 having an inlet communicating with the valve inlet and apply ing pressure to the closure member substantially equal to the opening force applied to the closure member by the pressure on the inlet side of the valve seat. The closure member 12, Fig. 1, co-operates with a cylindrical seat 11 in which pressure is reduced by a throttling member 28, Fig. 3, in the inlet 9a. Flow from the inlet also passes through the chamber 3 having inlet and outlet throttles 7, 8 which reduce the pressure to a value substantially equal to that in the seat 11. Pressure in chamber 3 acts through a rubber diaphragm 2 on an area of the closure member which is equal to that enclosed by the seat 11 to balance the forces on the valve. A space 4 surrounding the seat communicates with the outlet 10 and the closure member is guided by a ring 14 which also supports the edge of the diaphragm. The inlet 9 is supplied by a centrifugal pump 26, the valve keeping flow in the outlet 10 constant and returning fluid from the chamber 3 to the pump inlet 27. In a modification, the connection 6 forms the inlet to the chamber 3 and is fitted with a spring-loaded single-beat lift valve in place of the fixed throttle, the valve providing a constant pressure drop between the inlet and the chamber 3. A further modification contains a closure member in the form of a piston 12, Fig. 5, with labyrinth seals 12a, 12b, the diaphragm being omitted. A number of valves may be supplied from a single pump and the outlet from each chamber 3 be connected to the corresponding valve outlet.

The element 20 in filter 13 clogs quickly with coarse particles but lets through the fine particles normally passing the cleaner, and the pressure drop across the element is monitored. The air velocity in the probe may be less than that in the duct Fig. 9c, (not shown) so that the probe gathers coarse particles preferentially to fine. In Fig. 7 the duct includes a Venturi nozzle 17 arranged to cause a constant flow through the filter and through the other elements of a pneumatic bridge circuit. Normally Pb exceeds Pa and device 26 switches on audible or visual alarm 27 when clogging of element 20 equalizes Pa and Pb. Fig. 6 (not shown) illustrates a construction wherein pressure switch 26 is connected directly across filter 13. Fig. 4 (not shown) illustrates diagrammatically the use of a turbulence amplifier downstream of the filter 13 to enhance the result of filter clogging. Figs. 1 to 3 (not shown) illustrate how the air stream through filter 13 is generated with different engines, using the suction of the engine, or the pressure of an air compressor delivering the air from the air cleaner or an ejector operated by the exhaust or by a compressed air source. The air cleaner itself may be a filter, possibly combined with an oil bath or inertial separator.
