ABSTRACT:
An apparatus for intermittently atomizing a fluid with the assistance of a gas or a mixture of gases. The apparatus includes a cylinder having a cylinder head with a valve seat and at least one flow passage, a piston driven within the cylinder by a rotating crankshaft, an injection valve having a valve head and a spring element urging the valve head into engagement with the valve seat to close the flow passage. The injection valve generally includes an actuating surface that cooperates with the piston to mechanically open the valve when the piston reaches the end of its compression stroke. As a result, the present invention delays the start of valve opening until the piston maximizes the atomizing pressure within the cylinder thereby advantageously maintaining small fluid drop sizes. Additionally, flow passages formed within or proximate to the valve head provide a corridor through which the cloud of drops enter the combustion chamber. Altering the size, shape and orientation of the flow passages allows the shape and direction of the cloud of drops protruding from the flow passage to be varied for different applications. Finally, the injection valve preferably includes mechanical guidance at both its axial ends to reduce edge stresses and increase the durability of the valve.
