Definitions

  • the invention relates to a compressor for delivering a medium from a pressure chamber in a head through an outlet into a line, wherein a piston is arranged in the pressure chamber and the pressure chamber has a longitudinal axis along which the piston moves.
  • Compressors are known, and available on the market, in a wide variety of forms and embodiments. They generally serve to draw in a medium and convey said medium onward. In the present case, reference is made in particular to compressors used in conjunction with tire sealing agent which is introduced into a tire, wherein said compressors then generally also serve for inflating the tire.
  • a compressor of said type is required for example in DE 101 06 468.
  • DE 20 2006 008 219 U1 has described a compressor for generating compressed air, having a housing and having a drive which, via an eccentric shaft, moves a pressure piston that is guided in spring-loaded fashion in a cylinder.
  • DE 10 2008 061 31 1 has disclosed a compressor for delivering a gas out of a pressure chamber for the purposes of inflating a tire, wherein a piston is arranged in the pressure chamber so as to be capable of performing an oscillating movement.
  • the piston is assigned a transmission element which converts a rotational movement of a drive shaft into an oscillating movement.
  • the piston is assigned a seal which changes its spacing to a pressure chamber wall upon a change in the direction of movement of the piston. In this way, a gap is formed for drawing in the compressed air.
  • Said device is composed of a multiplicity of individual parts that must be assembled. - -
  • the problem addressed by the present invention is that of reducing the number of individual components and reducing the structural space.
  • the intention of this is to make the compressor more lightweight and to make the assembly process much cheaper and less susceptible to errors.
  • This refinement makes it possible for the piston to assume a predetermined spacing to the pressure chamber internal wall for the purposes of drawing in the medium, but to then close said spacing for the purposes of discharging the medium. In this way, a seal is simplified and is subject to the least possible loading.
  • the corresponding wobbling movement of the piston is effected by means of an eccentric.
  • the piston is connected to the eccentric by way of a piston rod, wherein said piston is preferably mounted obliquely on the piston rod.
  • said piston is then caused to perform a wobbling movement by means of the eccentric, the above-described spacing of the piston to the pressure chamber internal wall is produced and is closed again.
  • This may be realized with or without the seal, wherein, in a preferred exemplary embodiment, at least one annular seal is arranged on the circumference of the piston. It may however also prove to be expedient for an internal wall of the pressure chamber to be designed to be flexible, such that it can yield to a wobbling movement of the piston.
  • the eccentric is simply of disk-shaped form, with the piston rod being connected eccentrically to said eccentric.
  • the pressure chamber prefferably be provided, in the interior, with a sloping roof, wherein the slope is approximately matched to the slope of the piston. Said sloping roof then runs toward the outlet and conducts the medium in that direction.
  • a further part of the invention which is however preferably realized together with the first part, relates to the outlet itself.
  • Said outlet is no longer arranged at the tip of the pressure chamber but is instead situated radially to the side with respect to the longitudinal axis of the pressure chamber.
  • a valve which prevents a backflow of the medium.
  • the valve is in the form of a ball-type check valve.
  • an embodiment as a bicycle valve, with a corresponding connection nipple being equipped with a sheath which deflects under a pressure from the interior of the pressure chamber, such that the medium can penetrate between the nipple and sheath to corresponding openings which then issue into the line for the pressure medium.
  • the compressor it is the intention for the compressor to be used in particular for dispensing a tire sealing agent into a defective tire.
  • the line is then connected to a corresponding container for said sealing agent, such that, by the build-up of a pressure medium, said sealing agent is forced out of the container into the tire.
  • the line may then be connected to a valve of the tire, and the tire inflated.
  • figure 1 shows a longitudinal section through a head of a compressor according to the invention for delivering a medium, at a compression stage
  • figure 2 shows the longitudinal section through the head as per figure 1 at the top dead center of a piston
  • figure 3 shows the longitudinal section as per figure 1 , at an intake stage
  • figure 4 shows the longitudinal section as per figure 1 at the bottom dead center of a piston
  • figure 5 shows a partial section through a head according to the invention of a compressor for delivering a medium, in the region of a valve.
  • Figures 1 to 4 show a head 1 of a compressor according to the invention, in which head a pressure chamber 2 is formed.
  • a piston 3 moves in said pressure chamber 2 along a longitudinal axis A.
  • the piston 3 is connected to a piston rod 4 which is articulatedly connected to an eccentric 5.
  • the eccentric 5 is in the form of a disk that has a central point M.
  • the eccentric 5 rotates about said central point M, as indicated by the arrow 6.
  • the eccentric 5 drives the piston rod 4 along, said piston rod having an articulated connection 7 to the eccentric 5.
  • Said articulated connection 7 is arranged with a spacing to the central point M.
  • the piston 3 is arranged obliquely with respect to the -o- piston rod 4, that is to say said piston, at one side, is at an angle of less than 90° with respect to the piston rod 4 and, at the other side, is at an angle of greater than 90° with respect to the piston rod 4.
  • the piston 3 On its circumference, the piston 3 is provided with an annular seal 8 which serves for sealing off the pressure chamber 2 by virtue of the fact that, at certain stages of the movement of the piston 3, said annular seal bears against an internal wall 9 of the pressure chamber 2.
  • An outlet 10 for the medium to be delivered is provided laterally, that is to say radially, with respect to the longitudinal axis A.
  • the pressure chamber 2 forms a roof 1 1 that slopes obliquely toward said outlet 10.
  • the outlet 10 is assigned a ball 12 of a ball valve, which ball can be acted on by a corresponding pressure medium 13.
  • a nipple 14 is formed on the head 1 , onto which nipple there is pushed a hose 15 that forms a line 16 to a container for a tire sealing agent.
  • Said hose 15 may alternatively also be connectable to a valve of a tire.
  • the present invention functions as follows:
  • FIG. 1 shows the upward movement of the piston 3 in which the piston 3 causes a medium to be compressed in the pressure chamber 2 and forced through the outlet 10, and through the ball valve formed by the ball 12, into the line 16.
  • the medium is conducted to the outlet 10 by means of the sloping roof 1 1.
  • the annular seal 8 bears firmly against the inner wall 9 of the pressure chamber 2.
  • Figure 2 shows the top dead center position, in which the articulated connection 7 of the piston rod 4 lies on the longitudinal axis A.
  • the pressure chamber 2 has been reduced in size to the maximum extent possible, such that the greatest possible amount of medium has passed from the pressure chamber 2 through the ball valve into the line 16.
  • the piston 3 is adjusted into an oblique position such that the annular seal 8 is lifted from the internal wall 9 of the pressure chamber 2, such that an annular passage 17 is formed.
  • the medium to be delivered can be drawn through said annular passage 17 into the pressure chamber 2 as a result of the increase in size of the latter.
  • the head 1 may also be assigned a bicycle valve.
  • a flexible sheath 18 which may for example be composed of silicone.
  • Said sheath 18 is held by the hose 15 that is pushed on.
  • a connection between the outlet 10 and the line 16 in the hose 15 is realized via openings 19 in the sheath 18, which openings issue into a space 20 positioned upstream of the line 16.
  • a front region 21 of the sheath 18 is lifted from the nipple 14 and opens up a path for the medium to the openings 19, such that the medium can pass through the openings 19 into the space 20 and from there into the line 16.
