    Abstract: A valve assembly for a high-pressure pump has a valve housing formed with a central bore centered on a main longitudinal axis and a transverse bore extending radially from the central bore in opposite directions along a transverse axis and subdivided by the central bore into an intake transverse-bore part and an exhaust transverse-bore part. Respective intake and exhaust sleeves are provided in the intake and exhaust bore parts and in turn are provided with respective intake and exhaust valves. A flow-splitting sleeve is provided in the central bore and has a pair of lateral branches opening respectively in the intake and exhaust bore parts into the intake and exhaust sleeves. All three of these sleeves are received in the respective bores with radial play relative to the respective axes and form with the respective bores annular chambers that communicate with one another.
