Description

1 2

The invention relates to an oil flow regulator for oil - whereby an accumulation of water in the oil burner, in which the oil level in the regulator housing line 65 is avoided. On the outside by a float, which is the inflow valve above the housing 1, one running around it a bimetallic lever operated, held constant, bead 66 provided. The bead 66 is outside the whereby the float with a regulator around a fixed point 5 adjusts the oil level up to which the oil is inside The lever arranged rotatably in the housing is fixed to the control range in the normal position and the is bound and the bimetallic lever on the one hand loosely on an average of the normal control range entdem Swimmer rests and on the other hand speaks to him.

Inflow valve is in operative connection, according to patent The housing 1 of the regulator is connected to a housing

The invention is based on the object, the float 5 and a lever system for controlling a Safety device according to the main patent to the inlet valve 37 arranged. The lever system exists improve, in particular with simple means, the addition of a float lever 25, a rocker arm 40 Additional shut-off of the drain valve at the override and an intermediate lever 27. The float 5 is to reach the permissible limit values. 15 carried and supported by the float lever 25 According to the invention, this task is regulated and regulated within a regulating range that the lever system also includes a lower part of the inlet valve 37. When the level lock-out lever is exceeded and a drain lock lever gel area due to excessive oil inflow into the. Housing 1 is closed by the float lever 25

In a known control device (USA.-Pa- 20 next the rocker arm 40 is pushed and tilts in tentschrift 2 320 457) it is already known that its second switch position is. Be lever system when tipping over In addition, with a lower level output, the rocker arm 40 actuates the intermediate lever 27, which is the locking lever equip, whereby when falling below the intermediate lever 27, the inlet valve 37 fixed the control range of the float lever above the closes. The lever system is according to the invention in order Low-level lock-out lever and rocker arm, the locking 25, a low-level lock-out lever 67 and a drain valve closes. A transmission of this mechanism locking lever 68 extended. The low level locking lever the present invention is not possible, however, 67 is designed as a toggle lever and with a rivet borrowed, since in this known oil flow regulator with 69 pivotally mounted on the float lever bearing 23, a swimmer or with 2 swimmers an angle 70 of the float lever 25 summarizes behind Flow rate through the 30 arranged in the floor an approach 71 of the lower level locking lever 67, where-inlet valve is regulated, or this inflow by the lower level locking lever 67 with falling valve is completely closed when the floating float 5 and sinking float lever 25 mer falls below a certain control range. is raised. The lower level lock lever 67 under-on also arranged in the bottom of the controller, in turn, grips a provided on the rocker arm 40 This control mechanism does not bend the outlet valve 35, causing the rocker arm 40 to move into its actuated. second switch position is overturned. Thus becomes

A similar resel device that works with 2 floats even if the control range is not reached is known (USA.-Patent running valve 37 and the drain valve 73 tightly closed. 2 703 606), in which both the inlet valve and the other side are activated by the rocker arm 40 of the Abdas The outlet valve in the bottom of the control housing 40 is actuated by the flow stop lever 68 by the latter through is seen. One float is carried along by the rocker arm 40 opposite a cam 72 the rest of the controller room is pushed through a barrier and pushed down. This will separates, with this float in action and also the drain valve 73 tightly closed. The Abauf the drain valve acts when the tapered barrel lock lever 68 is at one on the underside Oil over the barrier acting as the upper level 45 of the housing cover 10 arranged bearing 74 getet. In addition, the drain valve is covered with this.

In contrast, in the case of the shut-off valve according to the invention, the drain valve 73 is fixedly regulated both closed with the help of a float.

To ventilate the oil drain 3 from the regulator to the burner, the spindle is hollow, with an opening 80 to the atmosphere always above a possible excess level in the controller lies. The opening 80 can also be outside the regulator are, preferably on the upper part of the spindle protruding from the housing cover 10 of the controller and can be protected from contamination by a hood 81.

Claims (1)

Claim: oil flow regulator for oil burners, where the oil level is kept constant in the regulator housing by a float that actuates the inflow valve via a bimetal lever, the float having a lever rotatably arranged around a fixed point in the housing is firmly connected and the bimetal lever on the one hand rests loosely on the float and on the other hand is in operative connection with the inflow valve, according to patent 1,286,677, thereby characterized in that the lever system also has a lower level lockout lever (67) and a drain lock lever (68). 1 sheet of CÜPY drawings
