- the component carrier points to his Scope at least one locking means. At least through one Area-wise deformation of the component carrier can Latching means can be brought into different positions.
- the locking means is wider at least in one of these positions arranged inside than in the undeformed Starting position, so that a first position of the locking means, in which there is a rest or in or with another component also a clamp connection can enter and a second, further internal position is provided, in which it from this additional component is free and the component carrier is mounted or disassembled / removed.
- the component carrier has one Recording area, which defines a cavity in which a component can be added.
- the component is involved preferably a valve or a Flow control valve of a thermostat assembly. On such prevents or allows a flow of liquid or coolant through the valve depending on it Temperature.
- the recording area can be made closed.
- two diametrically opposite struts can be provided.
- These arms each extend from a side strut inside and following up to an upper end area like this they also close off the recording area and can serve the component or the valve in the component carrier to keep.
- the arms can be both in this special Training but also in training other than a handle be carried out, for example by placing individual arms through a Intermediate piece to be connected.
- the locking means can be in different positions on the Receiving area, the side struts or the arms be provided. But are they in an upper one or too Edge area of the recording area or in such an area the receiving area or the side struts arranged, the Neighboring the poor, only a small part of the Receiving area / the side struts are deformed. About that in addition, the arms stand completely as a grip element or Attack area available.
- Uniform deformability and easy insertion and removal Removal results when the component carrier and in particular the recording area is symmetrical.
- a connector or similar it is favorable if the Cross section at least substantially annular or is circular.
- the component carrier from a deformable metal manufacture.
- a permanent and repeatable deformability but is by a complete or area Formation of the component carrier from a plastic, for example, a thermoplastic synthetic resin.
- Such a component carrier can be part of a Thermostat assembly, which is also a valve of the type described above.
- the thermostat assembly can also in one housing directly in an engine block or similar be included, the Thermostat assembly via the locking means of the component carrier the housing, etc. secured, for example, locked or can be jammed.
- the housing can have means that correspond to the Interlocking means interact.
- This can be, for example are one or more recesses or grooves if the Locking means are designed in the manner of projections. It is but a reverse education is also conceivable.
- a circumferential lip or an apron be provided on the component carrier, in particular on the Recording area.
- Such an apron can be on an inner surface of the housing and / or support.
- such an apron designed such that when the Housing / the valve is pressurized by the pressure is brought closer to the inner surface. The pressure is great enough and the apron designed accordingly flexible, so there can be a sealing connection between the apron and the inner surface. Can on an additional seal then be dispensed with.
- the pressure can also Recording area and the struts pressed outwards and thus the locking means are pressed into the groove.
- the housing tapers conically inwards and forms an inner surface which with the component carrier or also preferably cooperates with the apron in such a way that especially if there is pressure at the valve / housing, a sealing connection can arise.
- the thermostat housing and the thermostat assembly of the present invention is shown in Figures 1 and 2 and generally designated 10.
- the thermostat housing has one essentially cylindrical shell or a housing 12.
- the housing 12 is preferably a cast aluminum connector for a heat exchanger hose, through the coolant from one engine to one Heat exchanger flows.
- the exterior of the housing 12 has one raised bead 14 to hold a hose clamp on, which is used to attach the hose to the housing 12 to back up.
- a cylindrical inner surface 16 of the housing 12 is provided with a circumferential groove 18 which is used to to record a thermostat assembly described below.
- At the opposite end region of the housing 12 is a stop ledge 20 extending radially inwards intended. In the vicinity of the stop ledge 20, the inner surface has 16 has an inwardly tapering region 22.
- a one-piece holder or component carrier 24 is in the Housing 12 secured.
- the component carrier 24 has one annular receiving area 26, which has a side wall or includes an apron 28.
- the apron 28 engages conical region 22 of the housing 12 and forms a seal on it.
- the housing 12 and the receiving area 26 of the housing 12 determine an axis 30.
- the component carrier 24 has a pair of side struts 32 diametrically opposite sides, which differ from the Extension area 26 still extend above.
- the side struts 32 extend upwards and point outwards extending locking pin or locking means 34, which in the Engage groove 18 in the inner surface 16 of the housing 12. If the locking means 34 are in the groove 18, the Apron 28 of the receiving area 26 against the conical Area 22 of inner surface 16 pressed to seal form.
- a handle 36 extends upward from the side struts 32.
- the handle 36 has arms 38 which extend from an upper one End portion 40 of the side struts 32 inwards and then to extend above and outside to upper end regions 42.
- Intermediate piece 44 connects the two upper end regions 42 of the Arms 38.
- Arms 38 can be moved inward by it, as indicated by the arrows 46, pressed inwards become. This deforms the side struts 32 inward to the Withdraw locking means 34 from the annular grooves 18. As soon as the locking means 34 are withdrawn, the Component carrier 24 can be removed from the housing 12
- FIG. 4 An alternative embodiment of handle 36 is shown in FIG. 4 shown. Here the arms 38 extend upward, but not outwards, to the upper, distal end regions 42.
- the component carrier 24 is only a valve 50 designated flow control valve attached and so held in place in the housing 12.
- the valve 50 has a metal frame 52 which is attached to the component carrier 24 attached and sealed against this.
- the frame 52 points adjacent to the inner surface 16 of the receiving area 26 an apron 54 hanging down.
- the recording area 26 of the component carrier 24, a pair faces inwards extending projections 56, each one upward form directed stop surface 57.
- the projections 56 lie diametrically opposite each other and extend approximately 45 ° of the circumference of the component carrier 24.
- the valve 50 is in attached to the component carrier 24 by the valve 50, as in shown in the drawing, up into the receiving area 26 is pressed.
- the frame 52 of the valve 50 presses outwards on inclined surfaces 58 of each projection 56, the Receiving area 26 is deformed into an oval shape until the Valve 50 has passed protrusions 56.
- the component carrier 24 then returns to its original position.
- Other ways to fix the valve 50 to the component carrier 24 known, any with the component carrier 24 present invention can be used.
- the valve 50 has a sealing element 60, which on a Bar 62 in the receiving area 26 abuts a seal to form between the valve 50 and the component carrier 24.
- the Valve 50 also has a movable valve body 64 that of the frame 52 in a manner known for a thermostat and way can be moved. The valve body 64 moves axially between the closed, shown in the figures Position to an open position that allows fluid to to flow between the valve body 64 and the frame 52.
- valve 50 When valve 50 is closed, fluid pressure acts below the valve 50 on the apron 28 and presses the Apron 28 outwards against the conical area 22 of the casing 12. The pressure acts such that there is a seal between the housing 12 and the valve "self-activated”. If the Pressure of the liquid retained by valve 50 increases, so does the sealing force between the Component carrier 24 and the housing 12.
- the sealing element 60 between the valve 50 and the Component carrier 24 lies slightly radially inward of the locking means 34 on the side struts 32. Liquid pressure on the valve 50 thus causes a moment on the side struts 32, which forcing the locking means 34 into the grooves 18.
- the thermostat assembly consisting of the component carrier 24 and the valve 50 includes a handle 36 which is lightweight is manageable to the thermostat assembly from the housing 12 to remove to replace valve 50.
- the Thermostat assembly is removed by making the arms 38 simple be pressed inward to release the locking means 34 from the grooves 18 and then remove the thermostat assembly from the Lift housing 12.
- the provision of the conical area 22 in the housing 12 provides a seal between the housing 12 and the component carrier 24 is available.
