Title: Refuse compactors

Abstract: A refuse compactor having a container with a refuse compression space on one side of a pressure plate which is movable by atmospheric pressure, upon evacuation of the refuse space, in one direction through a compression stroke to compress refuse in the space. The pressure plate is movable in the opposite direction through a return stroke by either pressurizing of the refuse space or evacuation of a space, which may be a second refuse compression space, at the opposite side of the plate. The refuse compactor is adapted to be emptied by a conventional trash collection vehicle equipped with a trash bin elevating and inverting mechanism, e.g., a fork lift. The plate includes a wiper for prolonging the life of the pressure plate seal and the compactor includes a novel vacuum pump and valve system for operating the pressure plate.
