Abstract (en)
[origin: EP1887216A1] Thermal compensation arrangement (14) for an injection valve (10). The thermal compensation arrangement (14) comprises a casing (45) being coupable to the housing (12) and comprising a recess (54), a piston (46) axially movable in the recess (54) and being coupable to a valve needle actuator unit (16), the piston (46) having a lateral surface (60), a first front surface (58) pointing in axial direction and a second front surface (59) pointing in axial direction and away from the first front surface (58), a gap (65) between the lateral surface (60) of the piston and the casing (45), a first piston channel (61a) being arranged in the piston (46) and extending from the first front surface (58) to the second front surface (59) of the piston (46), and a second piston channel (61b) extending from the lateral surface (60) to the first piston channel (61a) thereby enabling a fluid flow through the second piston channel (61b) between the gap (65) and a recess section (66) extending in axial direction between the first front surface (58) of the piston (46) and the casing (45).
