Definitions
- the device with fuel injection and Lubricant delivery device for internal combustion engines can be used wherever a compact arrangement to be created for such a device, preferably with a chainsaw with several, if necessary also adjustable lubrication circuits and one Fuel delivery with higher pressure.
- the invention relates to a device Fuel injection and lubricant delivery system for internal combustion engines, preferably for Hand-held tools, such as chainsaws, with one on a crankshaft arranged or indirectly through the Crankshaft driven helical gear with a Counter wheel for driving the lubricant pump in engagement stands, with a piston of the lubricant pump one Bearing pin for the counter gear forms and one has frontal inclined surface against a Housing is held by an adjustable lifting pin, what about the flow rate of the lubricant pump is adjustable.
- Hand-held chainsaws have been used for lubrication the cutting chain is mainly controlled without valves Piston pumps proven.
- the oil pump in question has a cylindrical formed in a pump housing Pump chamber with one inlet opening and one Outlet opening and one in this pump chamber formed by a helical gear and a counter gear Gear rotatable pump piston on one Side is resiliently supported and on the other side has an end sloping surface that against an eccentric to the piston longitudinal axis Lift pin rests so that when the piston rod rotates an axial movement is generated which is used for pumping is exploited.
- the axially adjustable stop lets set different stroke of the pump piston.
- This lubricant delivery device is mostly as Auxiliary unit block together with the fuel injection flanged to the internal combustion engine.
- DE 37 35 711 A1 is a portable one Two-stroke powered, manually controlled Tool, such as a chainsaw or the like, with a pneumatically driven injection pump for Inject fuel and an intake manifold for the Combustion air and a low-vibration Handle housing for carrying and guiding the implement known in which the injection pump separately from Two-stroke engine is arranged in the handle housing and over flexible connections with the two-stroke engine in Connection is established.
- DD-PS 41 648 are lubricant pumps for Internal combustion engines are known, the two in a row arranged, rotating piston conveyor units exhibit. These lead to the constant stroke of one Engine speed of high reduction gearbox out.
- the first delivery unit supplies the lubricant and the second the fuel. Both media will mixed fed to the internal combustion engine, which as Two-stroke engine is executed.
- the invention Device is one of the counter wheels on both sides one lubricant feed unit each, preferably the two conveyor units of a lifting disc on one of the conveyor units are drivable. It already serves as the lifting disc called front oblique surface of the piston rod.
- one of the counter wheels can be on both sides one conveyor unit each, one of which of these funding units as continuously working Fuel pump and the other feed unit one in the flow rate is adjustable lubricant pump.
- the easiest way to adjust the stroke Conveyor unit consists of the as a stop serving lifting pin connected with a set screw is that can be rotated in a thread fixed to the housing and with which the axial position of the lifting pin is individual can be adjusted.
- the radial position of the Lift pin with respect to the longitudinal axis of the piston Change pump.
- the other counter gear on the opposite side of the crankshaft
- one permanently adjustable lubricant pump assigned.
- the adjustable lubricant pump that is on the same Side of how the fuel pump is arranged offers itself as a location for the actuator one axis above of the axes of the counter wheels, which are preferably transverse to Crankshaft axis lies.
- the counter gear driving the fuel pump becomes after a further embodiment of the invention axially guided on both sides in the housing block; the same applies for the one driving the lubricant delivery device Counter wheel.
- all lubricant pumps as adjustable Conveyor units are designed.
- the devices shown in Figs. 1 to 3 each have in a housing 10 on the Crankshaft 11 arranged helical gear 12 on opposite sides with counter wheels 13 and 14 in Intervention stands.
- the counter wheel 13 drives the Housing part 15 arranged lubricant pump 16 over the drive shaft 17, the drive shaft 17th the piston of the lubricant pump 16 at the same time Bearing pin for the counter wheel 13 forms.
- This piston 18a has an end sloping surface 18 as a lifting disk on against one in the housing 15 via a Adjustment screw 19 held lifting pin 20 abuts.
- At Rotation of the counter wheel 13 guides the drive shaft 17 oscillating up and down movements, whereby the (see Fig. 1) in the inlet port 21, 22 promoted Oil is pressed under pressure in the outlets 23, 24.
- the drive shaft 26 forms in a corresponding manner the opposite side a bearing journal for the Counter wheel 14 and serves to drive a fuel pump 27, the conveyor unit 28 via the inlet port 29 Sucks in fuel and pumps it into the outlet port 30.
- the two drive shafts for the lubricant pump 16 and the fuel pump 27 are parallel to each other aligned. This results in a compact dense design that is used in internal combustion engines for Hand-held tools are beneficial. Alternatively for this it would also be possible to drive the drive shaft 17th and 26 to be arranged in a V-shape.
- Fig. 2 Unit block through the crankshaft 11 that Helical gear 12 driven, which in the counter wheels 13, 14 engages.
- the drive shaft 17 serves as Bearing journal for the counter gear 13.
- the drive shaft 17 is part of a lubricant pump 16, which over the Inlet 21 the lubricant in the outlet port 23rd promotes.
- Corresponding same parts as the Lifting disc 18, the lifting pin 20 and the adjusting screw 19 and the spring 25 are the same Reference numerals as designated in Figure 1.
- On the opposite side serves the counter gear 14 and the Drive shaft 26 both for driving the fuel pump 27 and for driving the lubricant pump 31, the is arranged above the fuel pump 27.
- the Drive shaft 26 has one at its upper end frontal and serving as a lifting disc 32 Inclined surface against an adjustable lifting pin 33 is present.
- An actuating unit serves in the direction of the drive shaft 26 34, which has a manual operating lever 35 can be operated.
- the piston 36, the part of the Drive shaft 26, feeds through an inlet 37th lubricant entering the outlet 38 in after the State of the art for plunger pumps known Wise.
- the actuator 34 above the drive shafts 17 and 26 and across Longitudinal axis of the crankshaft 11 arranged.
- the adjustable actuator 34 for controlling the Pump delivery rate of the lubricant pump 16 below the Counter wheels 13 and 14 arranged while the Set screw 19 for the axial displacement of the previously described lifting pin 33 and thus to regulate the Delivery rate of the lubricant pump 31 is used.
- This too as an auxiliary unit block of an internal combustion engine, trained especially for two-stroke chainsaws Device is compact and uses Application of a few components through the Crankshaft rotation available during engine operation standing energy.
