    摘要： A vent valve flow fuse includes a valve cap (102) with a valve cap cavity (202) defined by one or more valve cap interior surfaces. The vent valve flow fuse includes a valve body (108) with a valve body cavity (206) defined by one or more valve body interior surfaces. The vent valve flow fuse includes a poppet (200) configured to at least partially fit within the valve cap cavity (202) and the valve body cavity (206). The vent valve flow fuse includes a spring (210) configured to fit within the valve body cavity (206) and to generate a resistive force against the poppet (200). The poppet (200) is in a first position when fluid having a first amount of fluid pressure enters the valve cap cavity (202) from a vent valve and engages the poppet (200). The poppet (200) is in a second position when fluid having a second amount of fluid pressure enters the valve cap cavity (202) and engages the poppet (200).

    摘要： The object of the invention is a device (100, 200, 200bis, 300, 300bis) for controlling a pilot pressure signal of hydraulic valves (3), for controlling the handling of gravitational loads (M), operating between two pilot lines (108, 109, 208, 209, 308, 309) between said valve (3) and a cylinder (1) adapted to sustain the load (M). The device (100, 200, 200bis, 300, 300bis) is a two-way and two-position valve for the communication between the cylinder stem-side pilot line (5) and the valve-side line (3) and is a valve which can take an open position and a partialized position, or anyway it never takes a closed position. The device (100, 200, 200bis, 300, 300bis) can take a position so that the fluid passage between the pilot lines (108, 109, 208, 209, 308, 309) is never completely closed.
