Abstract: A unit fuel injector suited to diesel engines, including an injection pump portion and an injection nozzle portion both constructed in a known manner and an improved electromagnetic injection control valve, which is a normally open valve to permit leak of fuel pressure from the pump portion and closes in response to an electrical pulse signal to thereby allow increase of the fuel pressure transmitted to the nozzle and resultant lifting of a valve normally closing the spray-holes. The injection control valve is provided with a back-pressure chamber to which fuel pressure leaking from the pump portion is transmitted through a pressure-balancing passage to act on the back end of the control valve member to thereby cancel a valve-opening force produced by the action of the same fuel pressure on the tip of the valve member.

Abstract: In an over-head cam type internal combustion engine, there is disposed a monoblock supporting member which is tightly seated on the cylinder head and supports thereon some of the essential parts of the valve operating mechanism, such as a rocker arm assembly and valve lifters. The monoblock supporting member is formed therein with a lubricant oil passage through which the lubricant oil for lubrication of the cam shaft, the cams on the cam shaft, the valve lifters and the rocker arms is carried.

Abstract: A label applicator and registration device for such an applicator are disclosed.The applicator includes along the path of a web including both a backing strip and a series of contact-adhesive coated labels, a web reel mounting, a brake for preventing overrun of the web from its mounting and to provide tension in the web, a registration device of generally triangular section, a dispense edge for detaching the labels from the backing strip, a take-up mounting for spent backing strip, and an elongate slide operable by a "stamp" action to actuate the various parts enumerated.The registration device may co-operate with projections which engage transverse edges of the device.The applicator can be used wherever price and similar labels are to be applied to goods. The registration device is applicable to label applicators whether powered or manual and is disposed upstream of any dispense edge of such applicators.
