An internal combustion engine 1 includes two cylinders 4 juxtaposed mutually adjacently to each other, two intake pipes 12, and two exhaust pipes 13.
There are two gas pathways through the apparatus.
The main water way comprises a water inlet way (100), two water distribution ways (200) and two water back-flow ways (300).
Each of the vacuum lines includes two mutually concentric pipes (1, 2) which define a vacuum space (3) therebetween.
Connections type: single line/two-lines (4
The outlet ends of both pipes are essentially coplanar.
The air is supplied to both detectors (D1, D2) by means of at least one suction unit (ASE), and the air speed in each pipe conduit is different.
To the intake side of the pump (1) are connected two return pipes (2, 3) allocated to the two wheel brakes (RL, FR), at least one return pipe (2) having a choke (4) and a return valve (5) opening towards the intake side of the pump (1).
At least one of the fluid lines (21, 24) is provided with at least two integrated electrical or optical lines for data and/or energy transmission.
The invention relates to a system for sealing a pipeline system, comprising a fluid-tight hose (1) for inserting into the area of the gap (2) between two pipes (3a, 3b) of a pipeline system to be sealed.
A dispenser for beverages that includes at least two product carrying lines (11, 12) and a peristaltic pump (13,14,15) acting to move a product through both lines.
Air cooling apparatus has a casing (1) containing two air flow paths (12, 14) through one of which (14) cooled fresh air is supplied to a house, while the other (12) receives stale air from the house.
At the interface between the two channels, the change in cross-section is preferably step-like.
Two lines (21, 22) lead from the distributor valve (14) to the consumer, each consumer line being connected by means of a distributor-valve piston (15) and a calibrated orifice (30) to a pump (85) and hence a reservoir.
The viscometer includes two adjacent parallel flow channels (46, 52) having relatively flat inner surfaces.
