A hydraulic fluid container for a hydraulic brake system, includes a hydraulic interface for connecting the hydraulic fluid container to another component. The hydraulic fluid container has a container housing, and the interface includes at least one connector arranged on the container housing, the connector received in a receiving seat of the other component. The connector has a channel which ensures a hydraulic connection between an interior of the container housing and the other component. A blocking device for blocking the hydraulic connection is provided, wherein the blocking device is opened when the connector is received in the receiving seat, the blocking device having a movable valve piston and a sealing element. The aim of the invention is to improve the blocking device and reduce the space requirement and assembly complexity. This is achieved in that the sealing element is designed to secure the position of the valve piston.

An unloader valve apparatus is provided for an air compressor. The unloader valve apparatus comprises a cylindrical piston having a longitudinal central axis and movable along the longitudinal central axis between a loaded position and an unloaded position. The unloader valve apparatus further comprises a stopper member pivotable about a pivot axis between a blocking position in which the stopper member blocks an unloader port when the piston is in the loaded position and an unblocking position in which the stopper member is not blocking the unloader port and is thereby allowing compressed air from the compressor to flow through the unloader port when the piston is in the unloaded position.

A railway car air brake hose support bracket has an upper portion with first and second attachment members, a lower portion and an air hose connector. The first attachment member enters into and engages a portion of an accessible compartment of an uncoupling mechanism housing below the coupler head, and the second attachment member is secured to an air brake hose support lug of the railway car coupler. The air brake hose connector engages an air brake hose assembly and suspends this hose assembly from the railway coupler at a predetermined distance above the rail bed. A method of installing the hose support bracket includes positioning the first and second attachment members, securing them in place, and attaching one or more railway brake hose units to the air hose connector, either before or after this positioning and securing of the upper portion of the bracket.

A housing projection is formed at a bottom of a second reservoir hole in a housing. According to this, a tip side in a press-fitting direction of a sleeve tends to deform inwardly in a radial direction and escape from the housing in a process of press-fitting the sleeve 88 into the second reservoir hole, since an inner slant part of the tip side of the sleeve contacts to a contacting surface of the housing projection, deformation of the tip side of the sleeve 88 is suppressed.
