The present disclosure relates to a valve block for a hydraulic brake system. The valve block for a hydraulic brake system includes a first valve row in which NO valve receiving bores to receive a plurality of NO valves are disposed, a second valve row in which NC valve receiving bores to receive a plurality of NC valves are disposed, a pair of pump receiving bores formed symmetrically to each other on opposite side surfaces to be disposed between the first and second valve rows and receiving a piston pump, a pair of first damping bores formed symmetrically to each other on the opposite side surfaces to be disposed above the first valve row and receiving a first pressure pulsation reducing device, a pair of second damping bores formed symmetrically to each other on an upper surface to be disposed above the first damping bores and receiving a second pressure pulsation reducing device, a pair of low pressure accumulator receiving bores formed symmetrically to each other on a lower surface, and a pressure sensor receiving bore formed on a front surface to be disposed adjacent to the pair of low pressure accumulator receiving bores.

A filter subassembly, having a first screen comprising a fabric that has mesh elements, the mesh size of which determines how effectively particles are prevented from penetrating therethrough, wherein a second screen is provided at a distance from the first screen, and the two screens are arranged in series.

Air brake tubing is provided having an air brake tube body comprising at least one layer formed from a composition comprising a copolyester, polyethylene terephthalate or polybutylene terephthalate; and a thermoplastic polyurethane.

A brake tube connector including a brake tube with a flare at an end, and a screw. The flare has a front portion with a front abutment surface, a rear portion with a rear abutment surface, and an intermediate portion between. The screw is arranged coaxially with the brake tube with an abutment surface facing the rear abutment surface. The rear portion of the flare has a frustoconical shape and an inclination angle between the rear abutment surface and a radial plane. The screw abutment surface is inwardly inclined at an angle between the screw abutment surface and a radial plane.

A circuit has a fluid line matrix and brake components connected to the fluid line matrix. Changes in the brake designs or brake functions can be carried out easily in that at least one interface is provided for connecting a distributor block. The interface is designed such that a configuration of the fluid line matrix can be formed by connecting or exchanging the distributor block. There is also described a distributor block which is suitable for forming a configuration of the fluid line matrix of the circuit by connecting to the at least one interface of the circuit.

A hydraulic oil resupply device (40) is provided between first accumulators (15F, 15R) in a manual braking operation circuit (11) and a second accumulator (25) in an automatic brake circuit (24). The hydraulic oil resupply device (40) resupplies hydraulic oil accumulated in the second accumulator (25) to the first accumulators (15F, 15R) at the operating of a manual braking operation by an operator. This configuration can suppress a rising speed of a brake pressure at the manual operation braking from being slow. Accordingly, in a vehicular brake system, it is possible to enhance a braking capability by the manual braking operation and improve the reliability.
