摘要:
A galley waste disposal system is provided for use with an existing vacuum collection system. The galley waste disposal system includes a basin for receiving galley waste and a discharge valve connected between the basin and a collection tank. The discharge valve is vacuum-operated and has an actuating port. An electrically-operated vacuum control valve is connected between the actuating port and a vacuum source. A flush element is also provided that is actuatable to produce a discharge command. A controller is operably connected to the control valve and is selectively operable in response to the discharge command to place the actuating port in fluid communication with the vacuum source, thereby to open the discharge valve. In addition, the discharge valve, vacuum control valve, and controller may be housed in an enclosure suitable for mounting remotely from the basin.

A spring acts on an operating member of a parking brake control and, when the brake is released, not only reduces the flyback energy resulting from the release but also stores such energy for use as a power assist during the next application of the brake. The spring acts on the operating member through a cam which removes the spring force from the operating member when the brake is fully released while progressively amplifying the spring force as the brake is progressively applied.
摘要:
A parking brake control in which a spiral spring is loaded between a sector and a pedal and unwinds to take up slack in the cable of a vehicle parking brake and tension the cable when a locking pin is removed following installation of the control and connection of the cable to the sector. A pawl coacts with the same sector to hold the sector in its brake-applied position and to enable release of the brake by pushing on the pedal. A cam is carried by the pedal and acts against the cable to produce a mechanical advantage which progressively increases as the brake is progressively applied.
