Zusammenfassung:	Passage defining means interconnecting a source of pneumatic fluid to a pneumatically operated control device. Flow control variable restrictor means is disposed in the passage defining means intermediate the source and the control device whereby the passage defining means has a part thereof disposed between the restrictor means and the control device. A variable vent means is interconnected to the part of the passage defining means and is responsive to pressure in that part of the passage defining means. The flow control variable restriction means tends to maintain a substantially constant pneumatic flow in the part of the passage defining means even though the pressure in the part of the passage defining means varies and/or the pressure of the pneumatic source varies.
