Definitions

  • the present invention relates to a valve for use in a coolant flow according to the preamble of claim 1.
  • valves can be used to control the coolant flow of an internal combustion engine in order to ensure an optimal coolant temperature in the fluid circuit, depending on the load case.
  • a fault such as a faulty control of the valve
  • the failure of the valve actuator it can lead to an undesirable increase in temperature of the coolant and thus to critical conditions, through which the internal combustion engine can be damaged.
  • the valve described in DE 10 2012 208 652 B3 has a fail-safe mechanism, which causes in an error case, the valve body in a predetermined Position is moved, in which the flow of coolant through the valve is maximum, so as to counteract overheating conditions in the cooling circuit.
  • valves are susceptible to contamination and sticking of the valve also results in failure of the cooling system.
  • the rotationally symmetrical valve body is rotatably mounted about the cylinder axis in a valve housing having inlet and outlet channels. Through openings in the outer area of the cylinder, the cooling liquid is controlled, whereby the flow rate is regulated by turning the valve body.
  • the interacting with the openings in the outer region of the valve body The channels are sealed by means of sealing bushes, which slide on the cylinder, the outer circumference.
  • a correspondingly high contact pressure of the socket is necessary. This causes correspondingly high adjusting forces of the valve body.
  • a valve which has a rotatably mounted in a valve housing, designed as a cylinder valve body having a passage in its interior and an opening in the cylindrical outer region, wherein in a region around the opening, the outer wall of the valve body is formed reduced, thus extends below the radius of the cylinder and thus according to a preferred embodiment forms a groove extending in the direction of rotation
  • the eccentrically extending groove results in a dependent of the valve body position reduction of the contact pressure against a sealing bush, resulting in an overall improvement in the adjustment, applied during the adjustment forces, moments.
  • the region, the recess, the groove with the outer wall running below the cylinder radius is eccentric, wherein the eccentric region, the distance decreases from the cylinder axis starting from the cylinder radius, has its smallest value in the region of the opening and then again eccentric increases to the cylinder radius.
  • the opening of the associated, reduced region of the opening is formed as an eccentric extending to the cylinder axis strip, which is oriented on the outer circumference of the valve body in the circumferential direction.
  • the width of the reduced area, the groove is greater than the width of the opening.
  • the width of the strip, the groove is adapted to the width of the sealing bushing.
  • FIG. 1 shows a view of the valve body
  • Figure 2 is a section through the valve body
  • Figure 3 shows the valve body with sealing bushing
  • Figure 4 is a section through the valve body with sealing bushing.
  • Figure 1 shows a perspective view of a cylindrical valve body VK of a thermal valve which is rotatably mounted in a cylindrical valve housing VG, not shown.
  • the valve body VK is designed in a manner known per se and has a passage D in its interior.
  • an opening 01 is arranged, which cooperates with a channel in the not shown, the valve body VK receiving valve housing VG.
  • the channel opens with a sliding sealing bushing DB lying against the outer circumference of the valve body VK on the valve body VK, as shown in FIG.
  • a further opening 02 is shown, which is designed conventionally, thus having no recess according to the invention.
  • the openings 01 and 02 are inlet passages, with the outlet AL being arranged in the direction of the passage D on the downstream side.
  • the outer circumference AU of the valve body VK has, in the area around the opening 01, a groove U designed as an eccentrically extending recess.
  • the groove U reduces the material thickness of the valve body VK around the opening 01, so that the outer circumference AU of the valve body is smaller in the region of the groove, while the inner circumference IU remains the same.
  • the strip-shaped groove U extends eccentrically to the cylinder axis, so that the distance to the cylinder axis decreases from the cylinder radius, in the region of the opening 01 has the lowest value and then increases again to the cylinder radius.
  • Figure 2 shows a section through the valve body VK, namely centrally in the direction of the cylinder axis. It is shown that the groove U has a width greater than the width of the opening 01, such that on both sides of the opening 01 is ever a circular bent portion B1 of the same thickness.
  • Figure 3 is a view of the valve body VK with sealing bushing DB and biasing spring F for pressing the sealing bushing to the opening 01.
  • Figure 4 shows the valve body in the region of the opening 01 - the sectional plane extends perpendicular to the cylinder axis. Recognizable is the both sides of the opening 01 eccentric running reduction of the cylinder wall.
  • the sealing bushing DB sits in the groove U, but does not extend to the boundary of the areas B1 and B2 but has a diameter d which is smaller than the width b of the groove U.
  • the sealing bush DB is a Hollow cylinder whose resting on the groove surface is adapted to the course of the groove.
  • the biasing spring F is seated on a seat S of the sealing bushing DB.
  • the contact force on the valve is controlled by the groove and thus a reduction in the power requirement of the valve is achieved.
