Problems solved by technology

One advantage of this pump is that it reduces the noise from the armature brake, but this pump is very complex and expensive to manufacture, the many moving parts of the pump and the pumping of fuel into the intake chamber create noise
Also, the pump is very bulky and not optimal for fitting inside the small supply of a household burner

Embodiment Construction

[0033] For purposes of illustration, the invention is embodied in the form of an atomizing unit for metering small quantities of fuel oil from a container (not shown) or priming pump (not shown) to a burner of an oil fired heating system or to a vehicle engine A liquid pump for metering fuel to the burner unit of the heater (not shown). In the description of the present invention, the term household should be understood in a broad sense to cover domestic burner installations in a domestic central heating system as well as in peripheral equipment belonging to the household, eg a vehicle or a boat.

[0034] The pump comprises a housing 2 for an electromagnet coil 17 which can be connected to a power source which provides a current cycle or pulse. The electromagnet is a standard part, eg Danfoss part serial number 71N0802. An armature cylinder 3 extends through the housing 2 and within the cylinder 3 an armature 4 is arranged to be reciprocated by an electromagnet. The armature...

Abstract

A reciprocating liquid pump (1) for delivery of liquid fuel to a domestic burner device comprises an electromechanical drive means acting on a plunger (5) to reciprocate the plunger in a pump chamber (7) of a pump cylinder (6). Liquid fuel is delivered from the pump during an active strode of the plunger. The active stroke is terminated by pressure relief means (15, 16, 23) which bleed the pump chamber (7) when the plunger is at a distance (d) from the maximum stroke end stop position.

Description

technical field [0001] The present invention relates to a reciprocating liquid pump for delivering liquid fuel to domestic burner installations, said pump comprising an electromechanical drive which is electrically driven and acts on a plunger for pumping in a pump chamber of a pump cylinder A plunger is reciprocated, whereby liquid fuel is delivered from the pump, the plunger has a maximum stroke end stop position. Background technique [0002] Liquid fuel burners, such as oil burners, are very common for domestic use. Usually this type of oil burner is a fuel pressure atomizing type which has a high pressure pump which delivers fuel at high pressure. These burners operate on the principle that when fuel under pressure expands through small orifices, the fuel is atomized into a cloud of very fine droplets, ideal for combustion. These burners are designed to operate at fuel pressures up to 40bar. The principle on which these burners operate requires that the pressure drop...
