Lubricant manifold

A fiber optic telecommunications device includes a rack for mounting a plurality of chassis, each chassis including a plurality of trays slidably mounted thereon and arranged in a vertically stacked arrangement. Each tray includes fiber optic connection locations and a cable manager coupled to the tray and also coupled to the chassis, the cable manager for routing cables to and from the fiber optic connection locations and defining a plurality of link arms pivotally connected such that the manager retracts and extends with a corresponding movement of the tray, wherein the link arms pivot relative to each other to prevent cables managed therein from being bent in an arc having a radius of curvature less than a predetermined value, each link arm defining a top wall, a bottom wall, and two oppositely positioned sidewalls, each link arm defining an open portion along at least one of the sidewalls and an open portion along the top wall for receiving cables therein, the open portions along the top wall and the at least one of the sidewalls communicating with each other.

A changeover valve for a single line parallel lubrication system includes a base housing, a first housing, and a second housing, which are distinct and separable units arranged to provide direct fluid communication between base housing, first housing, and second housing fluid channels. The base housing includes a plurality of fluid channels. The first and second housings each include a spool mounted in a cylindrical bore and hydraulically displaceable between ends of the cylindrical bore and a plurality of fluid channels fluidly connected to the cylindrical bore. The first and second housings are configured to mate with the base housing in a fluid seal. At least one of the base housing, first housing, and second housing includes and a relief valve in fluid communication with one or more of the plurality of base housing, first housing, and second housing fluid channels.

Hydraulic changeover valve

A pump housing includes an integral vent flow path extending between a low-pressure region and the reservoir. The vent path provides fluid communication between the downstream side of a throat seal dividing the low-pressure region from a high-pressure region and the reservoir. Lubricant flows through the vent path from the reservoir to the low-pressure region to provide lubrication to the throat seal.

This disclosure describes a fiber optic enclosure in which a cable entry port is sealed using a wedge that compresses a gasket that surrounds a fiber optic cable. As described herein, a fiber optic enclosure may include one or more entry ports through which fiber optic cables pass. As one of the fiber optic cables passes through one of the entry ports, the fiber optic cable passes through a gasket located in a receptacle behind the cable entry port. A wedge compresses the gasket, thereby compressing the gasket. When the gasket is compressed, the gasket exerts radial pressure on the fiber optic cable. In this way, the gasket forms a seal around the fiber optic cable.

Cable enclosure with sealed cable entry port

A telecommunications system includes a rack, telecommunications equipment mounted to the rack, and a cross-through trough extending between a front and a rear of the rack. The cross-through trough includes a sliding shuttle for pulling cables between the front and the rear. The sliding shuttle includes a cable clip for releasably holding one or more cables during movement between the front and the rear. The cross-through trough can be one rack unit (RU) in height, if desired.
