Definitions
- the invention relates to a particular form of design, in particular for use in connection with household refrigeration and / or Hermetic refrigerant compressor provided for freezers, namely the part of the compressor that the Refrigerant suction components inside the compression cylinder includes.
- the refrigerant suction check valve i.e. the valve that the refrigerant in lets in the compression cylinder and the backflow of the same the said cylinder prevented at the same time.
- a valve is in the form of a high-strength and highly elastic Steel existing tongue valve, which in technical jargon is also called spring valve, so in the following description generally from a spring valve or one Valve spring will be discussed.
- a spring valve is usually made of a small and extremely thin special steel plate, which has a curved incision in its central area, which delimits the section that the actual Valve spring, i.e. forms the moving part of the valve and releases and seals the suction hole in the valve plate.
- Such a board is held in place by the fact that respective perforations are provided at their corners, in which corresponding screw bolts can be screwed in, which are used to clamp the internal compressor body, the valve head, the valve plate, the valve spring and possibly interposed Seals are used so that the above Components practically held together as a single body become.
- the spring can also, as is known from DE 19 613 911 C1 is two laterally offset in the longitudinal direction of the spring, have arranged bent tabs, which in corresponding Immerse recesses. It is also possible as it is the training according to US 5 456 287 corresponds to the valve spring to form symmetrically and without bent tabs.
- FIG. 1 shows a sectional view of some with the Compressor head of connected components and Fig.la a view of the components mounted on the compressor head according to the invention
- FIG. 2 shows a plan view of the cylinder viewed Front of the valve plate according to this invention
- Figure 3 a Sectional view of the viewed according to the sectional area A-A Valve plate according to Fig.2
- Fig.4 is a plan view of the Cylinder viewed from the front with the valve spring provided valve plate according to this invention
- Figure 5 a Sectional view of the viewed according to the sectional area B-B Valve plate according to Fig.4
- Fig.6 is a plan view only of the valve spring according to Figure 4
- Fig. 7 is a plan view the front of the valve spring according to this invention provided and partially covered by the seal valve plate.
- Valve spring 2 from three different sections, one first section 5, with which the suction bore 12 can be sealed, a second section 6 against the valve plate in a blockable in a special manner described below and a third section 7, which is an elastic joint acts, which in turn the two sections 5 and 6 with each other connects, as can be seen from Fig. 6.
- the second section 6 is with two protruding, preferably parts 6a and 6b on the same axis 6c, the protruding parts 6a and 6b slightly to the side in relation to the level of the other sections of the spring valve are inclined, as can be seen in FIG. 5.
- the inner edges 3c and 3d are at least partially sharp-angled.
- the recesses and the protruding parts 6a and 6b of the valve spring designed, dimensioned and arranged so that the valve spring 2 according to the invention on the associated valve plate 3 can be attached.
- the two are outstanding Parts 6a and 6b bent elastically so that these in the aforementioned recesses 3A and 3B are inserted and there especially by jamming the protruding parts against the Inner edges 3c and 3d can sit tight and stable, like this in Figure 4 and in particular in Figure 5 is shown schematically.
- the first section 5 of the valve spring is stable in this Jamming position arranged exactly on the suction bore 12 so that he can close it tightly.
- Valve spring for more stable and reliable clamping of the above Valve spring is preferably a seal 13 in particular arranged as shown in Fig. 6, in its middle Section has an opening 14 which both the first Section 5 of the valve spring used to seal the suction hole 12, as well as the third, serves as an elastic hinge joint serving connecting section 7 leaves uncovered both protruding parts 6a and 6b completely covered, however this together with the jamming of the above described Hear protruding parts 6a and 6b specifically for the higher Stabilization of the entire valve spring in its correct working position, i.e. close to the valve plate, contributes.
