    • A device for compacting and dewatering moist refuse comprises a tube and a piston reciprocable therein. Varying consistency of the refuse matter will require a varying resistance to the compacting action of the piston. A throttling device within the tube comprises a number of plates which are swingable about an axis arranged perpendicularly to the tube, and are actuable so as to occupy a position practically level with the wall of the tube, or to a position in which they extend into the tube, respectively. The piston is operated by a double acting hydraulic ram, and the plates are operated by a further hydraulic ram. Both rams are connected to a source of pressure fluid, and are interconnected so the power stroke end of the further ram communicates with the return flow end of the piston ram, and vice versa. Two oppositely directed non-return valves are fitted in parallel in the conduit connecting the power stroke end of the further ram with the return flow end of the piston ram.
    • 一种用于压实和脱水潮湿垃圾的装置包括一个可在其中往复运动的管和一个活塞。 垃圾物质的不一致性将需要对活塞的压实作用的变化的阻力。 管内的节流装置包括可围绕垂直于管布置的轴线摆动的多个板,并且可致动以便占据与管的壁几乎一致的位置,或其延伸到 管,分别。 活塞由双作用液压油缸操作,板由另一液压油缸操作。 两个连杆都连接到压力流体源上,并且互连,使另一冲头的动力冲程端与活塞冲头的回流端连通,反之亦然。 两个相对方向的止回阀平行安装在导管中,连接另一个压头的动力冲程端与活塞压头的回流端。
