Abstract
A laminated spacer plate (10) for engines, pumps and the like comprises a plurality of metallic sheets (11-14), each having openings (15,16,17,24,40) preformed therethrough and secured together. The preforming of the openings through the individual sheets facilitates intercommunication of certain of the openings with passages formed within the spacer plate and eliminates the need for costly machining and related manufacturing operations normally required for the fabrication of a one-piece spacer plate.
Claims7
A method for preforming and mounting a laminated spacer plate (10) in an internal combustion engine to space the head (19) and block (18) thereof at substantially the thickness of a support flange (21) of each cylinder liner (20) employed in said engine comprising the steps of
- forming a plurality of openings (15,16,17,40) through each of a plurality of separate sheets (11-14),
- aligning said sheets (11-14) in superimposed relationship relative to each other to align at least some of said openings (15,16,17,40) with respect to each other,
- securing said sheets (11-14) together to form a laminated spacer plate (10) having a composite thickness at least substantially the same as the thickness of the support flange (21) of said liner (20),
- mounting said laminated spacer plate (10) in sandwiched relationship between the head (19) and block (18) of said internal combustion engine so that the laminated spacer plate (10) is seated adjacent the support flange (21) of each cylinder liner (20), and
- mounting a sealing gasket (22,23) between said spacer plate (10) and each of said head (19) and said block (18).
