Dosing pump used in a mobile heating device for conveying liquid medium comprises a damping device defined by a wall having a curved wall section which, as pressure is increased, is deformed into a flat or counter-curved form

摘要

Dosing pump (34) comprises a damping device (24) defined by at least one wall (36) for reducing pulsations in the medium conveyed by the dosing pump. The wall is formed by at least one curved wall section (38) which, as the pressure on the damping device is increased, is deformed in the direction of a flat or counter-curved form. An independent claim is also included for a mobile heating device for a vehicle comprising the above dosing pump. Preferred Features: The dosing pump has an elongated shape and the damping device is formed in an annular manner around a longitudinal section of the dosing pump.
