Definitions

  • This invention relates to a springless pressure valve, and more specically, to such a valve rdisposed to control the Vflow of fluid into a driving or working cylinder.
  • this invention will have utility any time it is necessary or desirable to control the iioW of a fluid under pressure.
  • the invention will largely be described as employed with pneumatic Staplers and nailers where it has been found to have great particular utility.
  • the valve of this invention serves to control the iiow of iiuid power into the working or driving cylinder of the device. But it is to be understood, and for that reason emphasized at the outset, that none of these factors is to be considered a limitation on the invention,V except as specifically set forth in the claims following this disclosure.
  • An equally important object of this invention is the provision of a firing valve of such a construction that at no time in its operating cycle are the exhaust and intake ports open together.
  • a further object of this invention is to provide such a valve adapted for use-'in a pneumatic stapler which used as minimum amount of air even though the driver actuating piston is both driven and returned by air.
  • a very important object of this invention is they provision of a springless tiring valve for a portable pneumatic stapler' such that the eiciency of the stapler will be greatly increased.
  • Still another object of this invention is to provide a springless tiring valve for a portable pneumatic stapler which will result inl substantially trouble free operation, and which may be easily replaced in the event thata defect should occur.
