Abstract: A vaporization burner for a heating device operated with liquid fuel, particularly a motor vehicle heating device, has a combustion pipe defining a combustion chamber, and an absorbent body arranged on a carrier, fuel being supplied to the absorbent body via said carrier. At least part of the carrier is not covered by the absorbent body, the uncovered area is provided with a through-opening. An ignition device is arranged behind the carrier and, preferably, extends into an ignition chamber, formed behind the carrier, by an ignition housing having a wall with an opening for supplying combustion air into the ignition chamber. Fuel, which has been vaporized by the absorbent body, reaches the ignition chamber via an opening in a portion of the carrier covered by the absorbent body and forms a combustible mixture. The mixture in the chamber is ignited by means of the ignition device, resulting in a pilot frame which extends through the through-opening in the uncovered area of the carrier.

Abstract: A piston pump, in accordance with several embodiments, comprises a suction chamber into which fluid medium enters from an inlet line via a suction valve, beginning at the outset of a delivery stroke of the piston pump, without a build-up of intake negative pressure during the delivery stroke of the piston, and is particularly adapted to prevent vapor bubble formation. A reliable pump closure is ensured in the vicinity of the pump outlet, independent of the spring action of a return spring, which bears against the piston, in that any fluid medium entering the suction chamber of the pump contacts the piston in a direction producing reinforcement of the outlet closure pressure. In accordance with preferred embodiments, the piston may be a partially hollow or entirely hollow piston instead of a solid one.
