Bill et al,

The diaphragm is pulled down against a spring-loaded valve at high vacuum, 
closing off the suction at idle.  At higher rpm and thus lower vacuum, the 
valve opens and applies manifold vacuum to the block.  It works very well 
and dries up the rear seal on  two of my engines.  It also stopped the 
occasional "fogging" of the neighborhood.  In this eco-conscious town full 
of Birkenstock-wearing, solar panel-washing, Prius driving folk, I was 
worried the townsfolk were going to march to my place with solar torches and 
organic mulch-rakes and speak harshly to me.  The diaphragms can still be 
had new.
