Definitions
- the invention relates to a lower cover of a cold room for pistons of internal combustion engines according to the preamble of claim 1.
- Such covers are z. B. known from US 3,221,718, US 4,377,967 A or from DD-PS 91162.
- Fig. 4 and Fig. 5 of US 4,377,967 is shown a standpipe 38, the one certain level above the cover or in to ensure the cup 70.
- the standpipe is made Metal and is by soldering or welding with the cover connected.
- DE-PS 91162 protrudes an injection tube 15 both up into the cooling channel as well as tube-like inlet downwards in the direction of an oil spray nozzle 17. The method of fixing the injection tube at Cooling channel is not recognizable. It is assumed that the injection tube also with the sheet metal cooling channel 13th welded or soldered.
- the invention therefore deals with the problem of a Standpipe or an inlet in a simple manner at a lower To secure the refrigerator cover of a piston. This Problem is solved by the characterizing feature of Claim 1. Advantageous developments are the subject the dependent claims.
- the Swissclipsende component is advantageously made of plastic, because in plastic spring-locking parts formed simultaneously with the production of the standpipe can be. As a manufacturing process is plastic injection molding appropriate. For higher loads, the admirclipsende Component also made of metal.
- inventive einclipsbare standpipes one deviating from the circular ring shape, in particular oval Cross-section on.
- the application is particularly intended for approximately circular lower covers of cooling ducts, according to DE 4208037 C by at least two parts on its circumference, radially fixed tensioned plate spring is formed, the radially inwardly and outwardly at axially opposite sides bears free on supports, as in the following in Fig. 1 shown.
- the lower cover of the refrigerator can also einstükkig with piston body, e.g. at welded Piston, in particular pistons produced by friction welding.
- a pendulum piston 1 has a cooling channel 2, the down through a cover 3 in the form of a two-part Disc spring is closed.
- a standpipe 4 - which is also designed as an inlet - fixed by snapping.
- the standpipe 4 is in the assembly from below into the cover 3 inserted. This is the area with the Locking lugs 5 elastically deformed inward and springs, as soon as the contact surface 6 rests against the cover 3, in the Snap position by the standpipe 4 with the directly below the locking lugs 5 lying groove in the cover. 3 locks.
- In its lower portion 7 is the standpipe widened funnel-shaped.
