Abstract: A fuel pressure regulator (10) for automobiles and the like comprises a body lower portion (11), an upper cover (12) and a resilient diaphragm (66) therebetween. The resilient diaphragm (66) separates an upper chamber (61) from a fuel outlet chamber (21). A passageway (22) extends between the fuel outlet chamber and a fuel inlet chamber (14). A spherical ball valve (29) and a cylindrical valve seat (26) are positioned at one end of the passageway (22). A removable plug (32) carries guide legs (33) for guiding the ball valve (29) and further carries a biasing spring (31) for biasing the ball valve (29) into a closed seating position. A piston (51) is positioned below the resilient diaphragm in the fuel outlet chamber (21) and has depending therefrom an elongated stem (52) which is received in a stem guide (53), with the stem guide having a tapered portion (54) extending into the passageway (22).

Abstract: A high speed punching apparatus for cutting parts out of generally flat stock with said apparatus including means for selectively adjusting the tool stripping force to accommodate different materials, means for avoiding possible cutting of an overlaying template, means for minimizing friction between the punching tool and associated die button, means for minimizing hangup of burrs on the work piece in the die button and also a punching tool having means for minimizing friction and for expelling chips cut from the workpiece.
