摘要： A valve having a flow control assembly with a bore having particle-deflecting features is provided. In one embodiment, the bore of a flow control assembly of a valve includes a contour shaped to deflect particles in a fluid stream through the valve toward the center of the fluid stream and away from a sealing surface of the flow control assembly. The bore may also, in some embodiments, create a Venturi effect that cleans sealing surfaces by drawing particles away from the sealing surfaces. Additional valve systems, devices, and methods are also disclosed.

摘要： A hydraulic actuator comprises a cylinder, a piston reciprocatingly received within the cylinder, a piston rod connected to the piston and a pressure release mechanism which allows hydraulic fluid to pass from a first side of the piston to a second side of the piston when the actuator encounters shock loading. This permits the piston to move. The pressure relief mechanism includes a passageway extending from the first side of the piston to the second side of the piston and a valve member adjacent to the passageway which releasably engages the piston. The valve member has a closed position where the valve member closes the passageway and engages the piston. A resilient member biases the valve member towards the closed position. A valve member limiter limits movement of the valve member away from the closed position. The resilient member has a rigidity sufficiently great so that movement of the valve member away from the closed position is more dependent upon the rigidity of the resilient member than upon a preload applied to the valve member.
