Abstract: A breakaway assembly may be provided. The breakaway assembly may comprise an upper joint connecting a boom tip to a structure (e.g. a plate.) The breakaway assembly may further comprise a first hinge connecting the boom tip to the structure and a second hinge connecting the boom tip to the structure. In addition, the breakaway assembly may comprise a pressure assembly connected to the boom tip and a lower joint connecting the pressure assembly to the structure. When a force is applied to the boom tip (e.g. from either side, fore or aft), the pressure assembly may be configured to oppose the force and one of the first hinge and the second hinge may be configured to release in response to the boom tip rotating.

Abstract: A valve may include a valve body, a valve spool, and a valve actuator arrangement. The valve body may comprise a bore and a first and a second passage to the bore. The valve spool may comprise a first end and a second end and be at least partially positioned and slidable within the bore. The valve spool may comprise a first and a second sealing region in sealing contact with the bore. A first chamber may be comprised, at least in part, between the bore and the valve spool at the first end. A second chamber may be comprised, at least in part, between the bore and the valve spool and between the first and the second sealing regions. A third chamber may be comprised, at least in part, between the bore and the valve spool at the second end. A third passage connects the first and the third chambers. The first and the second passages are both open to the second chamber when the valve is at an open position.
