Abstract
A piston-type fuel pump has two or more cylinder bores in a barrel. A piston in each cylinder bore has a port for admitting fuel into the cylinder bore. A swash plate assembly includes a wobble plate connected to each of the pistons. The wobble plate is given an oscillatory motion producing reciprocal movement of the pistons. A thin-walled metal bellows defines a closed interior space surrounding the pistons to prevent escape of fuel.
