Abstract
A mechanical self-timing valve is connected between a source of sanitizing solution and a milking machine to sanitize the milking machine between each milking operation. Initiation of the valve cycle is accomplished by pressing a button-type plunger to admit pressurized fluid to a cylinder and drive the piston and valve poppet to a flush position. Return of the poppet and piston to a drain position is resisted by pressurized fluid in the cylinder which is permited to bleed through a long, large diameter helical bleed conduit that winds around the plunger. In flush position, a sanitizing solution is directed through the valve, through a flexible milking line and through the claw and teat cups of the milking machine. In drain position, flow of sanitizing solution is blocked and the disconnected milking machine is gravity drained of remaining sanitizing solution, partly through the disconnected teat cups and partly through a valve drain port.
