Г54) КОМПРЕССОР ВЫСОКОГО ДАВЛЕНИЯG54) COMPRESSOR HIGH PRESSURE

1one

Изобретение относитс к компрессоростроению .This invention relates to a compressor industry.

Известен компрессор высокого давлени , содержащий корпус, полость которого подключена к источнику низкого давлени , шток привода, имеющий участки больщего и меньшего диаметров и снабженный прижимным устройством дл периодического взаимодействи щтока с плунжером, которое выполнено в виде установленной со стороны последнего на конце щтока подпружи- ю ненной втулки, и клапан, расположенный в канале дл сброса газа из зоны взаимодействи штока с плунжером 1.A high-pressure compressor is known, comprising a housing, the cavity of which is connected to a low pressure source, a drive rod having portions of larger and smaller diameters and provided with a pressure device for periodically interacting the rod with the plunger, which is made of a spring loaded at the end of the rod a sleeve, and a valve located in the gas discharge channel from the zone of interaction between the rod and the plunger 1.

В известном компрессоре разъединение штока с плунжером происходит за счет взаимодействи последнего с корпусом, что снижает надежность.In a known compressor, the separation of the rod from the plunger occurs due to the interaction of the latter with the housing, which reduces reliability.

Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.

Указанна цель достигаетс тем, что в компрессоре высокого давлени , содержа- 20 щем корпус, полость которого подключена к источнику низкого давлени , шток привода , имеющий участки большего и меньшего диаметров и снабженный прижимным устройством дл периодического взаимодействи штока с плунжером, которое выполнено в виде установленной со стороны последнего на конце штока подпружиненной втулки , и клапан, расположенный в канале дл сброса газа из зоны взаимодействи щтока с плунжером, участок щтока больщего диаметра выполнен съемным, расположен относительно участка меньшего диаметра с возможностью относительного осевого перемещени и снабжен сквозным каналом с размещенным в нем запорным органом, выступающим за торцовую поверхность участка щтока больщего диаметра со стороны, противоположной плунжеру.This goal is achieved by the fact that in a high-pressure compressor, containing a housing, the cavity of which is connected to a low-pressure source, an actuator stem having areas of larger and smaller diameters and provided with a clamping device for periodically interacting the rod with the plunger, which is designed as on the side of the latter at the end of the stem of the spring-loaded bushing, and the valve located in the channel for the discharge of gas from the zone of interaction of the rod with the plunger, the section of the rod of larger diameter is made removable , is located relative to the area of smaller diameter with the possibility of relative axial movement, and is provided with a through channel with a locking member placed in it protruding beyond the end surface of the section of the large diameter rod on the side opposite to the plunger.

Канал дл сброса газа может быть выполнен в обоих участках щтока, а клапан размещен в части канала на участке больщего диаметра.The channel for the discharge of gas can be performed in both parts of the brush, and the valve is placed in a part of the channel in the area of larger diameter.

Клапан расположен соосно запорному органу.The valve is located coaxially to the valve.

На торцовой поверхности участка щтока большего диаметра со стороны плунжера выполнены выступы.The protrusions are made on the end surface of the larger diameter shta side on the plunger side.

Claims

FIG. 1 shows a compressor, a longitudinal section; in fig. 2 - scissors on an enlarged scale, a longitudinal section; in fig. 3 - a section of a rod of larger diameter with a valve located coaxially to the locking member; in fig. 4 - separate valve and valve body; in fig. 5 shows the node I in FIG. 2; in fig. 6 is a view A of FIG. 5. The compressor includes a housing 1, the cavity 2 of which is connected to a low pressure source (not shown), a drive shaft 3 having a larger section 4 and a smaller diameter section 5 and provided with a clamping device for periodically interacting the rod 3 with the plunger 6, which is made installed on the side of the latter at the end of the stem 3 of the spring-loaded sleeve 7, and the valve 8, located in the channel 9 for the discharge of gas from the zone of interaction of the stem 3 with the plunger 6, section 4 of the larger stem 3 is made removable, is located section 5 of a smaller diameter with the possibility of relative axial movement L and provided with a through channel 10 with a locking member 11 in it protruding beyond the end surface 12 of section 4 of a larger diameter on the side opposite to the plunger 6, the channel 9 for gas discharge can be performed in both sections 4 and 5 of the rod 3, and the valve 8 is located in part of the channel 9 on the section 4 of a larger diameter and the valve can be located coaxially to the locking member 11, and on the front surface 13 of the section 4 of the slit 3 of the larger diameter from the plunger b side The protrusions 14. The valve 8 and the locking member 11 are provided with springs 15 and 16, and when coaxially arranged, 17-19 and the sleeve 20, with slots 21, a stepped ring 22 and a movable seat 23. Between the valve 8 and the ring 22 there is a gap P |, and the saddle 23 - gap 2 The compressor works as follows. During compression, the rod 3 moves until the sleeve 7 contacts the plunger 6. The pressure arising from this is released through the valve 8 through the channel 9 to the atmosphere. In this case, the rod 3 is tightly pressed against the plunger 6. During the return stroke, as a result of the interaction of the locking member I1 with the housing 1, a low pressure gas enters the junction zone of the plunger 6 with the section 4 of the rod 3. When this happens, their separation. The protrusions 14 provide sufficient passage when gas is discharged through valve 8; the presence of gap A reduces shock loads when the direction of movement of rod 3 is changed. Sleeve 20. Ring 22 and seat 23 provide alternate opening of channel 9 to release gas and channel 10 when the valve 8 and valve are coaxial body 11. Thus, the implementation of the rod of two sections, one of which is made channel with a locking body, will increase the reliability. Claim 1. Compressor of high pressure, comprising a housing, the cavity of which is connected to a low pressure source, a brush with water, having sections of larger and smaller diameters and equipped with a clamping device for periodic interaction of the rod with the plunger, which is made in the form of a spring-loaded bushing, and a valve located in the channel dd of the discharge of gas from the zone of interaction of the rod with the plunger, characterized in that, in order to increase reliability, a portion of the rod is larger diameter is removable, is relatively smaller diameter portion with the possibility of relative axial movement and provided with a through channel having arranged therein a locking body protruding beyond the end face schtoka bolschoy diameter portion on the side opposite the plunger.

2. A compressor according to claim 1, characterized in that the gas discharge channel is provided in both sections of the rod, and the valve is located in a part of the channel in a section of larger diameter.

3. Compressor on PP. 1 and 2, characterized in that the valve is located coaxially with the closure member.

4. The compressor according to Claim 1, characterized in that the protrusions are made on the end surface of the larger-diameter stem section on the plunger side. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 812961, cl. F 04 B 37/12, 1978.
