专利汇可以提供Method and apparatus for restoring the retractible barrier of an aircraft arrester专利检索，专利查询，专利分析的服务。并且A method and apparatus for retracting the retractible barrier of an aircraft arrester after it has arrested an aircraft and in which a portion of the kinetic energy of the arrested aircraft is stored by means of hydraulic pumps and by hydraulic accumulators or by air compressors and compressed air accumulators and used after arresting the aircraft, to drive hydraulic and pneumatic motors respectively for rewinding the band or line of the arrester and thus restoring the retractible barrier to the arresting position.，下面是Method and apparatus for restoring the retractible barrier of an aircraft arrester专利的具体信息内容。

权利要求

1. In an aircraft arresting system a device for restoring the barrier means to aircraft arresting position after completion of the arresting operation comprising: a. torque absorbing means from which the barrier means are unwound during the arresting operation and rewound thereon upon completion of the arresting operation; b. at least two compression means connected to said torque absorbing means and being alternately effective to pump pressure fluid to accumulator means for storing the energy produced by the unwinding operation and to drive said torque absorbing means to rewind said barrier means upon release of the stored energy; c. first passage means for individually connecting said compression means to said accumulator means and to a source of high pressure fluid; d. valve means in said first passage means effective to reverse the flow of pressure fluid to and from said accumulator means; e. an interconnecting passage having a constricted portion between said first passage means to provide flow of pressure fluid from said accumulator means during the rewinding operation, and f. separate valve controlled passage means effective to supply pressure fluid directly from the fluid source to one Of said compression means.

2. In an aircraft arresting system the method of rewinding the barrier means on the torque absorbing means, which comprises: a. utilizing the energy developed by the aircraft upon engagement with and unwinding of the barrier means for driving a plurality of compression means to alternately pump pressure fluid to accumulator means to store the energy therein and to energize the compression means upon release of the stored energy to drive the torque absorbing means; b. passing a restricted flow of the released pressure fluid through a constricted passage to one of the compression means, and c. passing additional pressure fluid for a limited period of time from a separate source to the compression means receiving the restricted flow so as to supply added torque required for starting the rewinding operation.
