Description

[Detailed description of the invention] This invention relates to a structural improvement of a horizontal vibratory compressor, which consists of a cylindrical container that houses the compressor body and is installed horizontally, and a lid that closes the left and right openings of this container. It is.

Conventionally, this type of compressor has been used, for example, in refrigerators, etc., but in order to prevent the vibration of the compressor itself from being transmitted to the outside during operation, it is configured as shown in Figure 1. It was customary. That is, the compressor main body A is suspended in a cylindrical container B by coil springs C ₁ and C ₂ that engage with the compressor side support pieces A 1 and _{A 2} and the container side support pieces B ₁ and B ₂ . It is housed and sealed by lids D ₁ and D ₂ . In addition,
E ₁ and E ₂ are mounting legs.

Since the conventional horizontal vibratory compressor shown in Fig. 1 is constructed as described above, vibrations of the compressor body A itself during operation are absorbed by the coil springs C ₁ and C ₂ and transmitted to the container B. can be effectively prevented. However, when this vibrating compressor is installed in an on-vehicle refrigerator installed in a car, for example, large accelerations occur when the car starts and stops, and large vibrations or shocks are generated when driving on rough roads. This causes the compressor body A to swing in various directions within the container B, causing the compressor body A to swing in various directions within the container B or the lid.
There was a serious drawback in that the compressor body A collided with the inner walls of D ₁ and D ₂ , producing unpleasant noise and damaging the compressor body A.

In order to solve the above-mentioned drawbacks, the present applicant first penetrated the through hole of the compressor side support piece provided in the compressor main body and fixed it to the container side support pieces provided above and below the cylindrical container. Utility Model Application No. 47-124008 (Utility Model Application No. 124008) discloses a device in which a coil spring is provided, and the compressor side support piece is fixed to the intermediate portion of the coil spring.
52-5289), but even this method cannot completely eliminate the above-mentioned drawbacks when large accelerations occur when a car suddenly starts or stops, or when large vibrations or shocks occur when driving on rough roads. There was a drawback that I couldn't do it.

The present invention has been particularly devised for the purpose of eliminating the above-mentioned drawbacks, and an embodiment of the present invention shown in FIGS. 2 and 3 will be described below. In this figure, 1 is a cylindrical container, and this container 1 is installed horizontally in a refrigerator or the like with mounting legs 2 and 2' fixed to the bottom of the container. 3 is accommodated, and the left and right openings are closed by lids 4 and 4'. Coil springs 5, 5' are interposed in a compressed state between the compressor main body 3 and the lids 4, 4', and cup-shaped holders are provided at both left and right ends of the compressor main body 3. Cylindrical shock absorbing members 6, 6' made of rubber or synthetic resin are fixed almost horizontally through pins 7, 7', and pin members 8, having pedestals 9, 9' are attached to the lids 4, 4'. 8' is fitted into the cylindrical buffer members 6, 6' so as to be slidable in the axial direction.

Since the horizontal vibratory compressor according to the embodiment of the present invention is constructed as described above, vibrations of the compressor main body 3 itself during operation are absorbed by the coil springs 5, 5' and the cylindrical buffer members 6, 6'. It is possible to effectively prevent the vibration from being transmitted to the outside of the container 1, and when this horizontal vibration compressor is installed in, for example, a refrigerator for a car, it is possible to prevent the vibration from being subjected to large accelerations when the car starts and stops. Even if large vibrations are applied from the outside of the container 1 when driving on a rough road, the compressor body 3 will only swing in the axial direction of the pin members 8, 8'. There is no collision with the inner wall of the container 1 or the lids 4, 4'. In addition, when the axial swing of the compressor main body 3 becomes large, the buffer members 6, 6' and the pedestals 9, 9' of the pin members 8, 8' collide with each other. , 6' causes no noise at all.

Figure 4 shows another embodiment of the present invention.
The difference from the embodiment shown in the figures is that the cylindrical buffer members 6, 6' are fixed to the lids 4, 4', and the pin members 8,
8' is fixedly attached to the compressor main body 3, and the other components are indicated by the same reference numerals as in FIG. 1, and the functions and effects are also the same, so a description thereof will be omitted.

As described above, according to the present invention, the horizontal type is made up of a cylindrical container 1 that houses the compressor main body 3 and is installed laterally, and lids 4 and 4' that close the left and right openings of the cylindrical container 1. In the vibratory compressor, coil springs 5, 5' are interposed in a compressed state between the compressor main body 3 and the left and right lids 4, 4', and a bowl-shaped spring is fixed to either one of the two. Cylindrical buffer members 6, 6' fixed almost horizontally via holders 7, 7'
The simple structure of the cylindrical buffer members 6, 6' and a pin member that is slidably fitted in the axial direction and is fixed to the other of the two, reduces the vibration of the compressor itself during operation. In addition, when this horizontal vibrating compressor is installed in a refrigerator for a car, it is possible to effectively prevent the vibration from being transmitted to the outside of the container. Even if a large vibration shock is applied from the outside of the container during running, the compressor body will collide with the inner wall of the container or lid, producing unpleasant noises, as in the case of conventional compressors.
Since accidents such as damage to the compressor body can be completely eliminated, this has a significant practical effect.
