Definitions

  • the invention relates to a valve in a filter the preamble of claim 1.
  • Such valves are called safety valves or by-pass valves used in filters for example for internal combustion engines, in particular in liquid filters, in which one in one Filter housing arranged filter element of the to be cleaned Fluid flows through and over the clean side of the filter element is derived again.
  • the filter element and possibly also further Parts of the filter can destroy, have such filters a safety valve, which when exceeding a pressure limit opens and the raw side immediately with the clean side of the filter element connects.
  • Such safety valves are simple for cost reasons and usually exist from a valve body inserted into a valve housing, which on one side of a valve spring in his Sealing position and on the other side from the pressure of the too Cleansing fluid applied to the raw side of the filter element becomes. If the pressure exceeds the closing force of the valve spring, the valve body is adjusted to its open position and the fluid can flow out via the safety valve.
  • the valve housing consists in such known safety valves usually made of aluminum and used as a press fit inserted into a receiving opening in the housing of the filter, which is also usually made of aluminum.
  • the invention is based on the problem with simple means to create a valve in a filter that is easy to set up is firmly anchored in the filter housing with little effort can be.
  • the valve is intended in particular also in plastic filter housing be usable.
  • the valve housing of the valve according to the invention has a radially projecting and elastic with respect to the housing outer wall deformable clamping collar, which in addition to the radial Component also with an axial component over the housing outer wall rises.
  • This obliquely protruding clamping collar is formed in such a way that one in a valve longitudinal plane lying tangent to the outer collar edge with the valve longitudinal axis an angle not greater than 90 ° is. In this way it is ensured that the valve body inserted in the manner in a recess in the filter housing can be that the clamping collar initially during the insertion movement until reaching the end seat of the valve is radially compressed due to its inherent elasticity, in the final position, however, can spread again.
  • the clamping collar is opposite, for example, at a 45 ° angle the lateral surface of the valve housing from.
  • the clamping collar is advantageously conically shaped, but can also be outside towards convex, whereby the insertion into the recess or recording in the filter housing is facilitated.
  • the clamping collar is preferably in the region of an axial Front side of the valve housing and is integral with the Valve housing formed. Parallel to the clamping collar can with small axial distance to this offset a circumferential Shoulder provided on the lateral surface of the housing be, wherein the axial section between clamping collar and Shoulder forms a groove for receiving a sealing ring. To the insertion of the valve, the clamping collar is compressed radially, whereby the inserted into the groove sealing ring for Appendix to the inner wall of the valve receiving housing recess in the filter housing and unfold its sealing function can. This is also supported by the fact that in advantageous Run the shoulder a little lower Diameter than the unloaded clamping collar.
  • the valve body including clamping collar, if necessary also the shoulder, is advantageously made of sheet metal. This inexpensive Execution allows the generation of a sufficiently high, radially outwardly directed clamping force from the clamping collar is produced.
  • At the clamping collar can produce a burr produced during manufacture in the outer collar area in a meaningful way for the Hooking the clamping collar when reaching the seat in the encompassing Wall of the housing recess to be exploited.
  • the valve 1 shown in FIG. 1 is expedient to a safety valve, which in a recess. 3 is inserted in a filter housing 2, wherein the filter housing 2 is part of a filter, in particular a liquid filter for a motor vehicle, for example for cleaning Fuel or of transmission or engine oil. Alternatively to this but also an application in an air filter into consideration.
  • the valve housing 4 of the valve 1 has a smaller diameter as the the valve receiving recess 3 in the filter housing 2, allowing a force-free insertion of the valve in the recess is possible.
  • a valve body 5 of a valve spring 6 in the direction of its closed position applied.
  • the valve body 5 can be axially outside be acted upon by the fluid to be cleaned, wherein the Valve body 5 against the force of the valve spring acting on it 6 axially displaced upwards in its open position if the pressure exerted by the fluid is the valve spring force exceeds.
  • the valve body 5 is adjacent to the open axial end face in valve 1.
  • a radially and axially protruding clamping collar 7 is formed, which part of the Ventilgetudewandung and is opposite to the lateral surface of the Valve housing 4 projects radially and axially.
  • This clamping collar 7 can deform elastically as part of its material elasticity and is the insertion of the valve 1 in the recess 3 radially compressed in the filter housing 2, resulting in a radially outwardly acting clamping force builds up, with the outer clamping collar edge pressed against the inner wall of the recess 3 becomes.
  • the valve 1 Due to the smaller diameter of the valve body 4 with respect to the recess 3, the valve 1 can be easily pushed into the recess until it reaches its final seat become.
  • the required clamping force is provided by the clamping collar 7 applied, which in the unloaded state a larger Diameter than the recess 3, wherein the clamping force extends in a line over the circumference of the clamping collar. If the material of the filter housing 2 is soft enough is due to the linear spreading of the clamping force the outer edge of the clamping collar 7 in the inner wall of the recess einkrallen, so that between clamping collar and filter housing a positive connection can be realized in the manner of a barb can.
  • a circumferential shoulder 8 is formed, which also protrudes radially relative to the lateral surface of the valve housing 4.
  • a circumferential groove formed in the one Sealing ring 9 is inserted, which expediently designed as an O-ring is and tolerances as well as different thermal expansions can bridge from housing and valve.
  • FIG. 2 is the due to its inherent elasticity in the direction of arrow 12 pivotable clamping collar 7 slightly convex, but may also be designed purely conical.
  • Across from a valve longitudinal axis 10 includes a tangent 11, which is applied to the outer clamping collar edge and in one the valve longitudinal axis enclosing valve longitudinal plane lies at an angle which is in an angle range between 0 ° and 90 ° and, for example, when the valve is inserted about 30 °.
  • the angle range is between 10 ° and 45 ° and takes one higher value than in the inserted state.
  • the valve housing 4 is constructed in two parts and has a lower portion on which the clamping collar 7 is formed, and a valve hood 14 placed on the lower portion, which is connected to the lower section via a beaded edge is.
  • the clamping collar 7 is opposite the housing outer wall 15 radially outward.
  • a rib 16 is arranged, a stop for the valve when inserted into the recess forms.
  • a stop for the valve when inserted into the recess forms.
  • the frontal region of the recess 3 is this extended over a chamfer 17, whereby the radially projecting Clamp collar 7 slightly compressed and better inserted can be; Also, the sealing ring 9 can be inserted easily become.
