Abstract

Suction line with concealed ventilation function The complete suction line (Fig. 2) is installed after removing the vented tank cap (Fig. 4) (A) in the filler neck (B) is turned so that (Fig. 4) the suction hose (H) extends into the oil tank (E) until just before the The floor is pushed where the oil can be drawn in, which is then extracted through the nozzle (I). During the extraction process, the oil level in container (E) drops and air can flow in from Outside. This is done through (Fig. 2) the connection (G) which has a vent slot (F) This slot is the milling in part (I) on the 3 / 8" thread. The air can now flow laterally along the outside of the hose (H) through the Insert into slot (F) and remove the oil along the same path as the oil level rises. The exploded view (Fig1) shows the individual parts of the complete suction line including... The internal thread (j) that was cut inside the connection (I) where the hose (H) is attached.

Description

[0001] Ventilated adapter in the compact version 3.0 with concealed ventilation, used to connect a suction line to operate those in the oil filler neck A mechanical hydraulic hand pump is used to turn the pump, which is also used for venting / ventilating the oil tank. This adapter is necessary. It preserves the ventilation function. This eliminates the need to attach an additional connection to the oil tank. The purpose This suction line allows an auxiliary pump to be operated in parallel to the hand pump, and the To simplify assembly.

Claims

[1] Suction line with concealed ventilation function The complete suction line ( Fig. 2) after removing the vented tank cap ( Fig. 4) (A) in the filler neck (B) turned so that ( Fig. 4) the suction hose (H) into the oil tank (E) until just before the The floor is pushed where the oil can be drawn in, which is then extracted through the nozzle (I). During the extraction process, the oil level in container (E) drops and air can flow in from Outside. This is done through ( Fig. 2) the connection (G) which has a vent slot (F) This slot is the milling in part (I) on the 3 / 8" thread. The air can now flow laterally along the outside of the hose (H) through the Insert into slot (F) and remove the oil along the same path as the oil level rises. The exploded view ( Fig.1) shows the individual parts of the complete suction line including. The internal thread (j) that was cut inside the connection (I) where the hose (H) is attached.
