Definitions
- the invention relates to a radial piston pump for high-pressure fuel supply in an internal combustion engine, having a compressor chamber arranged in a displacer housing, with reciprocating pistons arranged in a cylinder chamber, with a suction valve connected to a fuel supply line with a closing body loaded with a spring, an intermediate piece and a threaded pin and with a connected to a fuel discharge line pressure valve.
- a radial piston pump unit in which the suction valve is arranged in the transverse direction to the vertical axis of the reciprocating piston (DE 102 28 552 B4).
- This suction valve has the function of opening in as streamlined a manner as possible within a very short time and then reliably closing it again.
- the suction valve should be sealed and formsta ⁇ bil with an optimal dead space volume.
- the object of the present invention is to make the suction valve in a radial piston pump of the type mentioned so that it is streamlined, wear-resistant and dimensionally stable with optimization of Tot ⁇ volume space.
- valve mushroom formed in Flachsitzaus ⁇ tion with recesses well in the displacer unit is centered.
- the valve lift is ver ⁇ simplified by the distance between the valve head and the displacer unit, so that no stroke adjustment more erfor ⁇ sary is.
- the valve can be made for example of ceramic or sintered ⁇ material.
- the valve mushroom can have three channels distributed over the circumference, which pass through the base plate.
- the stopper plate may at the side remote from the waistband side at least two radi al ⁇ extending, having the through hole associated channels which are fuel-supply line in the region of.
- the suction valve may be arranged analogously to the known prior art in the transverse direction to the vertical axis of the piston and in the displacer housing.
- valve mushroom can displaceably store in a cylinder space of the displacer housing and with its spring-facing front side and the front of the cylinder chamber of the stroke of the suction valve defi ⁇ kidney.
- the threaded pin with a collar on the front side adjacent to the zone of the stop plate ⁇ in which the base plate and the two channels are arranged.
- the threaded pin may have, following the region of the threads, a circumferential groove into which a ring seal is inserted. This results in greater safety in the pump duration drove, since a high biasing force is achieved by the threaded pin with good sealing.
- the stop plate may be between a collar in the displacement housing and the threaded pin Ge ⁇ be arranged, to which the cylinder chamber of smaller diameter of the valve head is connected.
- Fig. 1 shows a cross section through a unit of Ra ⁇ dialkolbenpumpe
- Fig. 2 is an explosive view of the individual parts of the suction valve.
- a radial piston pump 1 is shown for high-pressure fuel supply in an internal combustion engine. It is particularly applicable to a common rail injection system.
- the radial piston pump 1 has a in a Verdrängergephase- se 3 arranged compressor chamber 4 on, as well as one way of which is arranged in a cylinder chamber 6 and reciprocable piston 7.
- This piston 7 can, for example, by a non-illustrated eccentric, known per se drive ⁇ wave corresponding to be moved.
- the radial piston pump 1 a suction valve 10, which is connected to a fuel supply line 9.
- This suction valve 10 can be arranged in the displacer housing 3 in the transverse direction to the vertical axis 0-0 of the piston 7.
- a pressure valve 16 which is connected to a fuel outlet line 17, is arranged above the piston 7. Via the suction valve 10, fuel is supplied from the low-pressure region to the pump piston 7. After the pressure has built up, the compressed fuel is discharged via the pressure valve 16. This fuel flows into a high-pressure channel and via a high-pressure line to a fuel distributor, for example a common-rail system.
- the suction valve 10 has a closing body 12, which is acted upon by a spring 11, in addition, a stop plate 22 and a threaded pin 14 is provided.
- the closing body 12 is formed of the suction valve 10 as the valve head 18, which according to FIG. 2 shows a waste-circuit bunch, 20 ⁇ 20 xx having 19 and subsequently three circumferentially distributed channels 20. These channels through ⁇ set a base plate 34, which may be formed as a bearing for the spring 11.
- This stop plate 22 has on the side facing away from the end collar 19 at least two radially extending, connected to a through hole 36 channels 24 and 24 x , which are in the region of the fuel supply line 9.
- the stop plate 22 is bounded on the back by the threaded pin 14, which has a region 28 for the threads according to FIG.
- valve head 18 supports displaceable bar in a cylinder chamber 38 of the displacer 3 and de ⁇ finiert with its spring 11 of the facing end face and the front of the foregoing cylinder chamber the stroke H of the suction valve 10th
- the threaded pin 14 following the region 28 of the threads, has a circumferential groove 30 into which a ring seal 32 is inserted.
- the suction valve 10 opens and the fuel can flow via the supply line 9, the base plate 36 and the channels 20, 20 ', 20' 'of the closing body 12 in the compressor chamber 4.
- the entire unit of the suction valve 10 is designed easy to install due to the special ⁇ re design, with no adjustment of the stroke and the compression spring 11 is required.
- the dead space volume is optimized, which pen Signsgrad leads to a better pump, and also the suction valve 10 total into ⁇ with low structural complexity streamlined ges ⁇ is taltet.
