Problems solved by technology

However, the hose can move or bulge in the engine bay when it is pressurized
The hose will then sit against other parts of the engine and the high temperature of other parts of the engine can cause damage to the hose

Embodiment Construction

[0027] Figure 1 shows a preferred embodiment of the hose of the present invention. The hose is prefabricated by a plurality of curved parts 1, 2 and a straight middle part 3. The circumferential surface of the hose is constituted by a groove 4 extending along the hose. In the first bend 1 of the hose, the groove 4 is spirally wound around the hose. In this part 1, shock and pressure can be absorbed in multiple directions. In the second straight part 3 of the hose, the number of spiral turns per unit length is relatively small, that is, the groove 4 basically extends along the hose. In the middle of the straight portion 3, the spiral groove 4 changes the direction around the hose, thereby forming a spiral groove with a larger number of spiral turns per unit length in the last bent portion 2 of the hose in a new direction.

[0028] Figure 2 shows a cross section of the hose. The cross-sectional shape of the groove 4 is substantially rectangular. The four grooves 4 are evenly distrib...

Abstract

The present invention relates to a medium-carrying hose, preferably for pressure medium and for use in, for instance, an engine unit, the wall of the hose comprising at least one wall portion (5). The wall portion is connected with at least one expansion portion (4) to form a continuous hose casing, so that the circumference of the hose is variable between a minimum value, when the expansion portion (4) is unexpanded, and a maximum value, when the expansion portion (4) is maximally expanded. The expansion portion (4) extends in the transverse and the longitudinal direction of the hose, the wall portions (5) being displaced relative to each other both in the transverse and in the longitudinal direction of the hose as the circumference increases and the expansion portion (4) expands. The invention also relates to a method for manufacturing such a hose.

Description

【Technical Field】 [0001] The invention relates to a hose carrying a medium, especially a pressure medium, and used in, for example, an engine compartment. The hose wall includes at least one wall part connected with at least one expansion part to form a continuous hose body. The circumferential surface of the hose can be changed between the minimum value when the expansion part does not expand and the maximum value when the expansion part expands to the maximum. [0002] The invention also relates to a method of manufacturing such a hose. 【Background technique】 [0003] The hose used in the engine compartment has to withstand various influences from the surrounding environment. For example, it has to withstand internal or external pressure or strong vibration generated by the engine during operation. The hose has very limited space in the engine compartment and similar devices. In order to make the engine space compact, it is usually necessary to prefabricate the hose and bend it...
