    摘要： Method and apparatus for controlling ''''run-in'''' train action and car coupling phenomena. A normally open valve means continuously maintains a relatively low level of impedance operable to resist movement of draft gear except when a ''''run-in'''' phenomena is encountered. When a ''''runin'''' phenomena is encountered, the valve means operates to increase an hydraulic impedance level acting on the draft gear so as to regulate draft gear movement during a ''''run-in'''' event. A disabling mechanism operates to maintain the valve means in a relatively open condition when high level buff coupling forces are imposed on the draft gear so as to provide a generally low level of impedance resisting draft gear movement during the application of high energy impact shocks to the draft gear.

    摘要： A cushioning apparatus for railway cars, which apparatus includes an hydraulic cylinder fixedly positioned in a sill, a double rod piston mounted in the cylinder and connected by socketed coupling with a drawbar, and a relief valve and return flow check valve arrangement located at least at one cylinder end. A scavenging means is operably disposed adjacent the piston rod and includes an annular fitment means.

    摘要： Cushioning apparatus for railway cars, which apparatus includes an hydraulic impedance mechanism having a high pressure cylinder and a low pressure cylinder. The high pressure cylinder is operable to transmit mechanical buff shock independent of the low pressure cylinder. A coupling apparatus for a railway car where a draft key is limited to a fixed increment of movement while buff movement of a coupler under the continuous control of an hydraulic impedance mechanism takes place over an increment exceeding the length of the fixed movement increment of the draft key. A method and apparatus for cushioning forces imposed on a railway coupling wherein draft key movement is limited to a first increment, hydraulically controlled buff movement of a coupler takes place over a second increment exceeding the length of the first increment, and mechanical force is transmitted through a high pressure cylinder of an impedance mechanism, substantially to the exclusion of forced transmission through a low pressure cylinder.

    摘要： An assembly which is intended to support a coupling hose of a railway vehicle having a fixed sill. A draft unit mounted in the sill is of the type including a draft housing mounted for longitudinal sliding motion within the sill. A coupling bar, having one end projecting outwardly from one end of the vehicle, is connected at its other end to the draft housing for transverse swinging motion about a vertical pivot axis disposed in a longitudinal median plane of the vehicle. The coupling hose is connected at one of its ends to a hose support member. This support member is supported by connecting means in spaced vertical relation relative to the coupling bar, in close longitudinal proximity to the one free end thereof. The connecting means is connected with the draft member to cause longitudinal motion of the hose support member relative to the sill upon corresponding motion of the coupling bar. This motion of the hose support member serves to generally maintain the relative positioning of the hose support member and the free end of the coupling bar during cushioning motion thereof. Guiding means is connected with the vehicle and with the connecting means to guide the connecting means and thus move the hose support member in a path disposed generally in the longitudinal median plane of the railway vehicle.
