摘要： A descent apparatus (13) for loads and/or persons. The apparatus includes a cable or rope (17) adapted to be fixed at an elevated location with the remainder of the cable or rope being wound around a pulley (12) rotatably mounted within a housing (11) via an axle shaft (13). The housing (11) is adapted to be attached to the load and/or person and the relative rotation between the pulley (12) and the axle shaft (13) is controlled by a closed circuit gear pump (14) the gears (25, 26) of which form transmission means between the pulley (12) and the axle shaft (13). The closed gear pump forms part of an hydraulic circuit which contains a speed control mechanism (33) provided by an orifice (30) in the hydraulic circuit which forms a constriction to control the speed of the pump and thus the seed of rotation of the pulley about the axle shaft and as a consequence the speed of the descent of the descent apparatus (10) as the cable or rope unwinds from the pulley. The speed control mechanism can also include a valve member (34) co-operating with a mating seat (35) in an end of the orifice, whilst the position of the valve member (34) is adjustable relative to its seat by a grub screw (36) to adjust the rate of flow of hydraulic fluid through the closed circuit gear pump and as a consequence the speed of descent of the descent apparatus.

摘要： A flow rate controller (40) for a closed fluid circulating system, the controller including an orifice (41) between the upstream high pressure fluid (42) and the downstream low pressure fluid in the system, a valve member (44) biased to partially close the orifice (41) and cooperating with a piston member (47) having one end exposed to low pressure fluid (51)downstream of the orifice (41) and an opposed end (52) exposed to upstream high pressure fluid via a bypass passage (53), whereby as upstream high fluid pressure (42) increases, the piston member (47) acts to move the valve member (44) further into the orifice (41) to reduce the fluid flow through the system. The flow rate controller (40) is used to control a descent device to enable people or loads to descend from elevated locations in emergency situations.
摘要翻译：一种用于封闭流体循环系统的流量控制器（40），所述控制器包括在所述上游高压流体（42）和所述系统中的所述下游低压流体之间的孔口（41），阀构件（44）关闭孔口（41）并与活塞构件（47）配合，活塞构件（47）具有暴露于孔口（41）下游的低压流体（51）的一端和经由旁路通道暴露于上游高压流体的相对端（53），由于当上游高流体压力（42）增加时，活塞构件（47）用于将阀构件（44）进一步移动到孔口（41）中，以减少通过系统的流体流动。流量控制器（40）用于控制下降装置，以使人或负载在紧急情况下从升高的位置下降。
