Abstract
A hydraulic advancement/postponement assembly is operably coupled to a first ejector plate and to a second ejector plate. The hydraulic advancement/postponement assembly includes a first hydraulic cylinder having a first housing defining a first volume and a first piston, the first housing connected to the first ejector plate and the first piston connected to a fixed element. The hydraulic advancement/postponement assembly includes a second hydraulic cylinder disposed in fluid communication with the first hydraulic cylinder, the second hydraulic cylinder having a second housing defining a second volume and a second piston, the second housing connected to the first ejector plate and a second piston connected to the second ejector plate.
Claims14
A hydraulic advancement/postponement assembly, comprising:
- a first hydraulic cylinder having a first housing, the first housing having a first internal diameter and a first length defining a first volume and a first piston at least partially disposed within the first volume, the first housing configured to be connected to a first moveable element and the first piston configured to be connected to a fixed element;
- and
- a second hydraulic cylinder disposed in fluid communication with the first hydraulic cylinder and having a second housing, the second housing having a second internal diameter and a second length defining a second volume and a second piston at least partially disposed within the second volume, the second housing configured to be connected to the first moveable element and the second piston configured to be connected to a second moveable element;
- wherein the first volume is substantially equal to the second volume, the second internal diameter being less than the first internal diameter and the second length being greater than the first length.
