A telescopic apparatus for a human-powered vehicle comprises a first hydraulic chamber, a second hydraulic chamber, a valve member, a cam member, and an actuator. The second hydraulic chamber is configured to be in fluid communication with the first hydraulic chamber. The valve member is configured to control a fluid communication between the first hydraulic chamber and the second hydraulic chamber. The cam member is rotatable about a rotational axis to move the valve member in a movement direction. The actuator is configured to rotate the cam member. The actuator includes an output shaft rotatable about an actuation rotational axis. The actuation rotational axis is offset from the rotational axis as viewed in the movement direction.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

Gas admission valve assembly includes a housing, an elongated valve guide disposed within a central bore of the housing, a valve including a valve stem slidably disposed within the valve guide and a valve head selectively engagable with a valve seat of the housing to control flow between gas entry and exit openings into a housing entry chamber. First and second stem seals are disposed at opposite ends of the valve guide in sealing engagement with the valve stem between the valve stem and the central bore of the housing distally and the valve guide proximally.

A valve actuating assembly is provided that comprises a cam holder positioned within a valve body of an internal valve, a cam operably coupled to the cam holder and configured to engage a valve stem of the internal valve for moving the internal valve between a first position and a second position, and an actuating shaft extending through at least a portion of the valve body, rotation of the actuating shaft causing rotation of the cam holder and the cam, wherein the actuating shaft is removably coupled to the cam holder such that the actuating shaft can be decoupled from the cam holder and removed from the valve body, the cam holder and the cam being configured to remain positioned within the valve body when the actuating shaft is decoupled from the cam holder and removed from the valve body.

A pressure relief valve configured to vent a pressurized tank in the event of a fire is provided. The pressure relief valve includes a body, a vent passage, a plug and a latch. The vent passage is disposed through the body. The vent passage can be placed in fluid communication with an internal volume of a tank and with the atmosphere. The plug is moveably mounted in the vent passage. The latch has a blocking member disposed in contact with a control end of the plug in a first configuration and out of contact with the control end in a second configuration. The second configuration allows movement of the plug in the vent passage. One or both of a shape memory alloy wire and a trigger piston is configured to actuate the latch from the first to the second configuration. The shape memory alloy wire is configured to shorten when exposed to a temperature above a threshold temperature. The trigger piston moves, e.g., by a pressurized gas, in a trigger actuation passage to actuate the latch from the first configuration to the second configuration.

An evaporative emissions control system includes a first vent valve configured to selectively open and close a first vent, a second vent valve configured to selectively open and close a second vent, a fuel level sensor configured to sense a fuel level in the fuel tank, a pressure sensor configured to sense a pressure in the fuel tank, an accelerometer configured to measure an acceleration of the vehicle, and a controller configured to regulate operation of the first and second vent valves to provide pressure relief for the fuel tank. The controller is programmed to determine if a refueling event is occurring based one signals indicating the fuel level is increasing, the pressure in the fuel tank is increasing, and the vehicle is not moving, and open at least one of the first and second vent valves based on determining the refueling event is occurring.

A vent shut-off assembly configured to manage venting on a fuel tank includes a main housing, a poppet valve and an actuator. The main housing is positioned outside of the fuel tank and selectively vents to a canister. The poppet valve is disposed in the main housing and includes a plunger that provides over pressure relief (OPR) and over vacuum relief (OVR) functions. The actuator assembly can be housed in the main housing and includes a cam assembly having a cam shaft that includes a cam having a profile that one of opens and closes the poppet valve. When the poppet valve is in the closed position, vapor is precluded from passing between the fuel tank and the canister. When the poppet vale is in the open position, vapor is permitted from passing between the fuel tank and the canister.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

The present invention relates to a hydraulic and/or pneumatic multi-coupler connector of the type comprising at least one pair of couplers inserted into a containment body and equipped with a lever actuated mechanism comprising an actuation lever maneuverable by the user for the relief of the residual pressure of the couplers and the connection thereof to corresponding male couplers.

A valve for applying an emergency brake of a rail vehicle includes a valve housing, an actuation member to be activated by a user, an actuation rod connecting the actuation member with a valve head, wherein the valve head is adapted to abut on a valve seat, a guidance for guiding the actuation rod being provided within the valve housing, and a first spring adapted to push the valve head against the valve seat, wherein the actuation rod includes a first groove and a second groove, and wherein a first following member is provided between the actuation rod and the guidance, being adapted to stably rest in the first groove or the second groove.
