A housing for an electropneumatic modulator for an electropneumatic brake system for a vehicle, includes: an electric chamber configured to receive at least one electrical and/or electronic component of the electropneumatic modulator from a first side of the housing; and a receptacle chamber which is arranged opposite the electric chamber and is configured so as to receive a relay piston and a guide device for guiding the relay piston from a second side, opposite the first side, of the housing, in which the housing is formed in one piece. Also described are a related electropneumatic modulator and a method for making the electropneumatic modulator.

An air cleaner assembly comprises a filter element and a housing assembly. The filter element comprises a filter media for filtering a fluid and a first endcap positioned along a first end of the filter media and through which a first filtered air flow portion flows. The housing assembly at least partially contains the filter element and comprises a cover that defines a first outlet through which the first filtered air flow portion flows to a downstream device. The cover comprises a noise reduction device that receives the first filtered air flow portion and dissipates sound waves traveling upstream from the downstream device.

A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

A non-return valve having a valve opening spring is positioned between an unpressurized brake fluid reservoir and a brake master cylinder of a hydraulic vehicle power brake system having an externally-powered brake pressure generator. The non-return valve allows for a flow-through in the direction of the brake master cylinder and blocking against a return flow from the brake master cylinder into the brake fluid reservoir starting at a counterpressure in the brake master cylinder specified by the valve opening spring.

An electrically insulated cable including: a core electric wire; and a covering layer covering the core electric wire; wherein: the core electric wire includes a plurality of insulated wires; the insulated wires each include a conductor and an insulating layer covering the conductor; and the covering layer contains a crosslinked polyethylene-based resin and a flame retardant in the front surface side thereof.

A pump includes: fluid delivery portions each including a volume variable mechanism, a first port and a second port, and a valve mechanism; and a pump flow path formed by the three or more fluid delivery portions being connected in series, in which a movement range of each of pistons includes a maximum volume position, a minimum volume position, and a switching position, and the pump flow path is configured such that a closing movement process (movement between switching position and minimum volume position) in which the piston moves between the switching position and the minimum volume position by driving of a drive device is sequentially shifted from a first inlet/outlet port toward a second inlet/outlet port or from the second inlet/outlet port toward the first inlet/outlet port among the fluid delivery portions

A cuboidal hydraulic block of a hydraulic power unit of a slip-controlled power vehicle braking system includes a power cylinder borehole, a receptacle for a pedal travel simulator in parallel to the power cylinder borehole, perpendicularly through two large sides of the hydraulic block, and perpendicularly to a master brake cylinder borehole. The master brake cylinder borehole extends, in parallel to an upper transverse side, from one longitudinal side of the hydraulic block to an opposite longitudinal side of the hydraulic block. In an intended installation and usage position, an electrical plug connection is situated beneath a lower transverse side of the hydraulic block.

A pneumatic device (1) has at least one venting path (10) for venting the pneumatic device (1) in an outflow direction (R1). The venting path (10) includes a first volume (12), through which a flow can pass, a first compressed-air passage (14), and a sealing mechanism (18). The first compressed-air passage (14) pneumatically connects the first volume (12) to a pressurized part (16) of the pneumatic device (1). The sealing mechanism (18) changes between a normal state (Z1) and a sealing state (Z2). In the normal state (Z1) a flow can pass through the first compressed-air passage (14) both in the outflow direction (R1) and in an oppositely directed inflow direction (R2). In the sealing state (Z2) a flow can pass through the first compressed-air passage (14) only in the outflow direction (R1).
