Definitions
- the invention relates to a piston pump with at least one piston arranged axially displaceably in a housing, with a rotatably mounted drive shaft for driving the piston, with an inlet channel and with an outlet channel. Furthermore, the invention relates to an advantageous use of the piston pump.
- Piston pumps known from practice usually have a crankshaft as a drive shaft connected to the piston via a connecting rod.
- the inlet duct and the outlet duct each have valves.
- the valves can be positively controlled via a camshaft or have a spring element and can be controlled via the pressure generated by the piston in the housing.
- By means of an intended diameter and stroke distance of the piston and the speed of the drive shaft very high delivery volumes can be generated at a high delivery pressure.
- a disadvantage of the known piston pump is that it requires a very large installation space and is very complex to construct.
- a control control pressure piston performs a combined rotating and back and forth movement and has a control groove on its outer surface.
- a disadvantage of this piston pump is that it is also very complex and is only suitable for small delivery rates.
- the invention is based on the problem of designing a piston pump of the type mentioned at the outset in such a way that it is of particularly simple and compact construction and enables a high delivery rate at a high delivery pressure. Furthermore, an advantageous use of the piston pump is to be created.
- the first-mentioned problem is solved according to the invention in that the drive shaft has a control curve with at least one upper reversal point and one lower reversal point, that the piston is guided in the control curve and that a transmission element extends from the piston through an elongated guide in the housing extends into the control curve.
- the control curve is sinusoidal over the circumference of the shaft and has an upper and a lower reversal point.
- the piston is moved in one direction and when rotated through the next 180 °, the piston is moved in the opposite direction.
- This design of the control cam drives the piston as in the case of the piston connected to the crankshaft via the connecting rod.
- the delivery pump according to the invention therefore has a high delivery volume at a high delivery pressure.
- a connecting rod mounted on the piston and on the drive shaft is avoided thanks to the invention.
- the piston pump according to the invention therefore requires a particularly small number of components to be assembled and is therefore of a very simple construction.
- the direction of movement of the piston is preferably arranged parallel to the axis of rotation of the drive shaft.
- the piston of the piston pump according to the invention can be rings or sealed with a membrane against the housing.
- twisting of the transmission element can be easily prevented if the transmission element is guided through an elongated guide in the housing.
- the piston pump according to the invention requires only a single control curve for a plurality of pistons if a plurality of pistons are arranged concentrically with the drive shaft.
- the inlet channel could, for example, be arranged in the housing and have a control valve or be controlled by the movement of the piston.
- the piston pump according to the invention is particularly compact if the inlet channel penetrates the piston and has a check valve.
- the outlet channel preferably has a check valve in the housing.
- the piston pump according to the invention has a particularly low axial overall height if the check valve of the inlet channel and / or a check valve of the outlet channel are / is designed as a diaphragm valve.
- the check valve of the inlet channel and / or the check valve of the outlet channel has / has a valve body which is guided in a longitudinally displaceable manner and opposite a valve seat.
- the valve body can be biased against the valve seat by a spring element.
- the valve bodies can also be controlled by the pressure in the housing without spring force.
- the manufacture of the piston requires particularly little effort if a recess provided in the piston for receiving the transmission element has a circumferential groove.
- the circumferential groove can, for example, be rectangular, trapezoidal or have a circular section.
- the piston could, for example, be made in one piece with the transmission element.
- the piston can be manufactured particularly easily without radially protruding components if the piston has a pocket corresponding to the transmission element for receiving a partial area of the transmission element.
- the piston is secured against twisting and the connection between the transmission element and the piston can, for example, be mounted hydrostatically.
- Another advantage of this design is that, in contrast to the recess being designed as a circumferential groove, the pocket can provide surface support for the transmission element.
- the piston pump according to the invention is therefore particularly low in wear.
- the pocket can, for example, be designed as a cylindrical bore or as a conical bore or have a spherical shape corresponding to the transmission element.
- the transmission element can be pressed into the pocket and thus avoid a relative movement of the piston with respect to the transmission element. this leads to a further reduction in wear of the piston pump according to the invention.
- the piston pump according to the invention can be composed of particularly inexpensive components if the transmission element is designed as a ball.
- the control curve preferably has a cross section designed as a partial circle.
- twisting of the transmission element can be reliably avoided if the transmission element is designed as a rotationally symmetrical sliding block.
- the control curve preferably has a rectangular or trapezoidal cross section.
- the piston pump according to the invention is structurally particularly simple if the guide in the housing is arranged on a straight line connecting the axes of symmetry of the piston and the drive shaft.
- the transmission element can be provided with particularly large dimensions without contributing to increasing the radial dimensions of the piston pump according to the invention if the guide is arranged in the housing outside the straight line connecting the axes of symmetry of the piston and the drive shaft.
- a play of the transmission element in the guide of the housing or in the control curve can be easily compensated if lateral contact surfaces of the guide of the transmission supply element in the housing and / or the control cam are biased against each other.
- the transmission element is guided particularly precisely and wear is kept particularly low.
- control curve can be made particularly long if the drive shaft in the region of the piston has an edge which at least partially surrounds the piston radially on the outside and the control curve is arranged radially on the inside on the edge.
- the drive shaft thus encloses the piston.
- the particularly long control cam is subject to particularly low wear.
- the drive shaft can be designed with a particularly low level
- control curve has at least one different curve function during an intake stroke than during an exhaust stroke. This helps to reduce vibrations of the piston pump according to the invention.
- the control curve and thus the intended sequence of movements of the piston over the angle of rotation of the drive shaft is freely definable thanks to the invention. nable.
- the control curve can also be composed of several curve functions.
- x l
- m 240 °
- r 120 °
- the piston is moved when the drive shaft rotates 240 ° upwards to the upper reversal point and the subsequent rotation of the drive shaft 120 ° downwards to the lower reversal point.
- the second-mentioned problem namely the determination of an advantageous use of the piston pump, is solved according to the invention by use as a fuel pump in a structural unit with a motor for driving the drive shaft.
- FIG. 1 shows a longitudinal section through a piston pump according to the invention
- Figure 2 is a sectional view through the piston pump of Figure 1 along the line II - II.
- FIG. 3 shows a sectional view through a further embodiment of the piston pump according to the invention
- FIG. 4 shows schematically a longitudinal section through a further embodiment of the piston pump according to the invention
- FIG. 1 shows a longitudinal section through a fuel pump with a drive shaft 2 mounted in a housing 1.
- the housing 1 has a cylindrical bore 3 with a piston 4 which is axially movably guided therein.
- the drive shaft 2 has a control cam 5 for receiving a partial area of a transmission element 6.
- the transmission element 6 penetrates an elongated guide 7 in the housing 1 which is arranged parallel to the axis of rotation of the drive shaft 2 and projects into a recess 8 in the piston 4 which is designed as a circumferential groove.

- the piston 4 is shown in the drawing at the upper turning point 19.
- the transmission element 6 slides in the control cam 5 and in the guide 7 of the housing 1 and thereby displaces the piston 4 away from the outlet channel 10.
- the valve 12 closes in the outlet channel 10.
- a vacuum is created in the space delimited by the piston 4 and the housing 1, as a result of which the valve 11 in the inlet channel 9 opens and a medium to be delivered is sucked in.
- the valve 11 closes in the inlet channel 9. If the drive shaft 2 is rotated further via the lower reversal point 20, a pressure is created in the space delimited by the piston 4 and the housing 1, which pressure presses the valve body 18 of the valve 12 in Exhaust channel 10 pushes away from the valve seat 16. The medium to be pumped is thus expelled through the outlet channel 10.
- FIG. 2 shows in a sectional view through the piston pump from FIG. 1 along the line II-II that a total of three pistons 4, 4 ′, 4 ′′ are arranged in the housing 1 concentrically around the drive shaft 2.
- the housing 1 is thus designed as a cylinder bank and carries a plurality of pistons 4, 4 ', 4''.
- more than three pistons 4, 4 ', 4' * can also be arranged in the housing 1.
- Each of the pistons 4, 4 ', 4'' is connected to the single control cam 5 of the drive shaft 2 via a transmission element 6, 6', 6 ''.
- the guides 7, 7 ', 7 "' for the transmission element 6, 6 ', 6 1 ' are designed as bores.
- FIG. 3 shows a further embodiment of the piston pump in a sectional view, which differs from that from FIG. 2 primarily in that the axes of symmetry of the guides 7, 7 ', 7' 1 lie outside one of the axes of symmetry of the drive shaft 2 and the pistons 4, 4 ', 4''straight lines are arranged. Furthermore, contact surfaces 21 of the guides 7, 7 ', 7 "' which are in contact with the transmission elements 6, 6 ', 6' 1 are arranged on tensioning elements 23 which are prestressed by spring elements 22. The transmission elements 6, 6 ', 6"' are thus in the guides 1, 7 ', 7''biased.
