A hydraulic lock for a hydraulic system includes a flow control valve and a second check valve. The flow control valve having a first inlet, a first outlet, a first check valve and a flow restrictor, each of the first check valve and the flow restrictor being communicably coupled to the first inlet and the first outlet and being arranged in parallel between the first inlet and the first outlet. The second check valve having a second inlet and a second outlet, the second inlet being communicably coupled to the first outlet, the second check valve further having a ball seating surface having an aperture there through, a ball, and a resilient member biasing the ball towards the ball seating surface to seal the aperture, the aperture being communicably coupled to the second inlet and the second outlet.

A hood lifting assembly according to various implementations includes a re-latching feature that allows two slidably coupled plates to be reset, or locked, relative to each other by moving a head of a pin into a keyhole opening of a keyhole slot defined in one of the plates. In an initial position, the head of the pin is spaced apart from the keyhole opening, allowing the pin to move along the keyhole slot from the initial position to a deployed position and then to a reset position. In other implementations, a hood lifting assembly includes an energy absorbing feature. One exemplary energy absorbing feature includes a plate defining an elongated slot that has a narrowed width portion through which a pin travels during movement from the initial position to the deployed position.

A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

A system for moving an aircraft door from an open position towards a closed position. The system includes an aircraft door actuator, an input receiving primary power from a primary power supply to power movement of the aircraft door from the open position towards the closed position, a secondary power supply to power the aircraft door actuator to move the aircraft door from the open position towards the closed position, and a controller configured to cause the secondary power supply to power the aircraft door actuator to cause the aircraft door actuator to move the aircraft door from the open position towards the closed position, on the basis of a determination that insufficient primary power is available from the primary power supply via the input to move the aircraft door from the open position towards the closed position.

A door opening and closing operating system includes a pressurized fluid source (102), two fluid control push pull valves (144a), (144b), and a double acting cylinder (160) which is mounted to the movable element of a door (66) mounted within its adjacent frame (62) for the purpose of opening and closing the door. This system utilizes two push pull valves connected fluid-wise to opposite sides of the piston. Activating or energizing one push pull valve while deactivating the second push pull valve connects the first cylinder chamber to the pressurized fluid source, and vents the second chamber, thereby pushing the piston in a first direction, which pushes the door in a first direction. Energizing the second push pull valve and de-energizing the first push pull valve has the opposite effect, and moves the piston and attached door in a second direction opposite the first direction.
