  • -Myinvention further comprises a cylinder head with a plate of a durable metal having thevalve seatstherein andrec eiving the injector bushing or seating as a gas tight fit therein, the said plate being located by a screw or screws or by the bushing or seating in a machined recess in the cylinder head and being clamped in position between the head and the cylinder to make gas tight joints therewith when the head is secured upon the cylinder.
  • My invention further comprises the provision of the durable metal plate with the valve seats therein between adjacent surfaces of the cylinder head and the cylinder, the said plate being located in position upon the head by the injector bushing and then clamped between the head and the cylinder to make gas tight joints therewith by the usual cylinder head holding down bolts or studs which pass through the plate.
  • My invention further comprises the arrangement in which the fuel sprayer bushing or seating is a press fit in or screws into the durable metal plate.

If the plate c; is not lacpress 'fit" in the recess in'the' head; locating screws may be used to secure it to the head'ar d' facilitate handling and machining butthe maintenance of gas tightjoints between plate, head and cylinder is due to the holding down pressure of the studs orbolts.
  • the cylinder head has the usual inlet and exhaust passage g and h therein and the valve guides i and 7.
  • the fuel sprayer or injector is positioned as usual in the cylinder head so that the spray is delivered into the engine cylinder.
  • a headed bushing it which provides a seat for the sprayer or injector m may be pressed through the sprayer recess in the head into the plate a in which it is a good press-tight fit so that there is no pressure leakage from the cylinder along the bushing.
  • the bushing may be threaded through the sprayer recess and screwed into the plate a and serve as additional means for holding the plate to the head to make the desired gas tight joint at the bushing.
  • the bushing if not concentric with the plate, may also serve as the plate locating means.
  • the plate with the valve seats therein can be withdrawn from the cylinder head and renewed when desired without damaging the head.
  • the plate a with the valve seats b and c therein is located between the cylinder head and the cylinder e and is held in place by the usual holding down studs.
  • a single plate may serve for a multi-cylinder engine.
  • the plate for a series of cylinders may be located in position upon the head by the bushings k together with if desired screws to facilitate handling and machining as with the previous construction.
  • My invention is not concerned with engines in I which the cylinder head is of built up construction with a durable metal wall for the valve seats and fuel valve bushing.
  • my improvement is not concerned with engines in I which the cylinder head is of built up construction with a durable metal wall for the valve seats and fuel valve bushing.
