Definitions

  • the heat exchanger is always flowed through in a lower temperature range and that at least with a predominant volume flow rate.
  • the heat exchanger should be acted upon in the lower temperature range by the complete oil volume flow.
  • a three / three-way switching valve 1 is provided in a housing which may be part of a filter and / or heat exchanger housing in an oil circuit of an internal combustion engine of a motor vehicle.
  • This switching valve 1 has three ports, namely a port A, is supplied by the lubricating oil from the circuit when using the switching valve 1 in the oil circuit of an internal combustion engine, a port B, from which the lubricating oil is passed to the engine and a port C, through the cycle oil can be introduced, which has previously flowed through a heat exchanger.
  • the oil flows that can be supplied through the ports A and C the switching valve 1, are controllable, depending on the temperature of the in the switching valve. 1 entering oil and a pressure difference between the terminals A and C.
  • the switching valve 1 comprises a thermostat as an expansion element 2, which is displaceable longitudinally displaceable under the load of a first compression spring 3 in a longitudinal direction stepped cylindrical cavity.
  • the expansion element 2 is composed of two telescopically mutually displaceable components and that of a first component 4 and a second component 5. These two components 4, 5 move mutually relative to each other in temperature changes.
  • the expansion element 2 is supported above particularly low temperatures exclusively via the first component 4 axially in the housing and against the force of the first compression spring 3. This type of support is shown in Fig. 1B, C ,.
  • the second component 5 of the expansion element 2 is supported in a region directly upstream of the connection A on the housing. This support is such that thereby the flow cross-section of the terminal A is sealed, so that in this state of the expansion element 2, a flow through the port A is blocked.
  • a closure function of the expansion element 2 is a prerequisite that the change in the total length of the expansion element by a displacement of the first component. 4 takes place within the second component 5 of the expansion element 2 due to temperature.
  • a radially outwardly projecting third annular collar 9 is provided.
  • the ring cage 6 is acted upon axially on both sides by a respective compression spring and at one end by the first compression spring 3 and the other end by an oppositely acting, on the second component 5 of the expansion element 2 supporting second compression spring 10.
  • the stiffness of the second compression spring 10 exceeds that of the first Compression spring 3.
  • the annular collar of the second region 8 of the ring cage 6 has radially inward distance from the outer circumference of the second component 5 of the expansion element 2, so that oil can flow through the annular gap given thereby.
  • the ring cage 6 At the axial end of the ring cage 6, which is defined by the second region 8, the ring cage 6 has axially extending webs 11, which are elastically deformable in the radial direction and have inwardly projecting barbs 12 at their free ends.
  • the ring cage 6 is mounted on the second component 5 of the expansion element 2 in such a way that the barbs 12 engage behind the third annular collar 9 provided on the second component 5. In this way, the second compression spring 10, the ring cage 6 maximum up to a stop of the barbs 12 to the third annular collar 9 in the direction of the first compression spring 3 facing the end of the expansion element 2 move.
  • annular collar of the second region 8 of the annular cage 6 and the third annular collar 9 of the second component 5 of the switching valve 1 are dimensioned such coordinated that they at an axial contact an oil flow between the inner circumference of the cylindrical recess of the switching valve 1 and in the axial region of this cylindrical recess located second component 5 of the expansion element 2 lock, that means that in this state in this area no oil can flow.
  • the switching valve according to the invention allows a total of four flow modes with respect to the above four temperature ranges.
  • Circulating oil is supplied from a reservoir 14 to an internal combustion engine 15 via the switching valve 1.
  • the extracted from the reservoir 14 oil flow leads a line 19 to a filter 16, which may be equipped with a lying in a first bypass line 20 by-pass valve 18.
  • a heat exchanger 17 is arranged with a bypass line 21 bypassing this in line 19.
  • the heat exchanger 17 is the conventional radiator of the internal combustion engine 15 in a motor vehicle.
  • the first bypass line 20 is likewise connected on the one hand to the second bypass line 21 and on the other hand to the region of the line 19 lying between the filter 16 and the heat exchanger 17.
  • connection A for flow through is completely closed and the connection C is completely opened.
  • the closure of the connection A that is a closure against oil coming from the filter 16 is achieved by contacting the annular collar of the second region 8 of the annular cage 6 with the third annular collar connected to the second component 5 of the expansion element 2.
  • this switching state is a shortening of the clamping length of the second compression spring 10 before.
  • the above-indicated temperature ranges may be defined as follows, for example lower temperature range: up to 80 ° C, medium temperature range: above 80 ° C to 120 ° C, high temperature range: above 120 ° C.
  • the switching valve 1 represents practically a further development of that cited in the introduction to the prior art DE 199 43 294 A1 in which, in addition to a constructive deviating structure, in particular the function has been extended in the lower temperature range.
  • the set out for a switching valve in that prior art font operating conditions of the oil circuit in which that previously known valve is used therefore, in principle, also apply to the subject of the invention development. It is therefore expressly made to the statements in that older document as background to the present invention reference.
