Abstract

Two pairs of the screw rotor (1-4) are located inside the single housing (5). One pair acts as compressor with the outlet leading directly into the inlet for other pairs acting as expander.

Description

516 2933 Ett andra skruvrotorpar bestående av en malerotor 3 samverkande med en femalerotor 4 används för att låta bränsle-lufiblandningen efter antändning expandera under avgivande av energi. 516 2933 A second pair of screw rotors consisting of a grinding rotor 3 cooperating with a femoral rotor 4 is used to allow the fuel-lu mixture to expand after ignition while emitting energy.

De två skruvrotorparen är placerade i ett gemensant hus 5 på ett sådant sätt att utloppet 6 för det av de första skruvrotorparet komprimerade mediet löper direkt in i inloppet 7 för det andra skruvrotorparet där det efter antändning får expandera. Den korta direkta förbindelsen ger låga strömningsförluster.The two screw rotor pairs are placed in a common housing 5 in such a way that the outlet 6 of the medium compressed by the first screw rotor pair runs directly into the inlet 7 of the second screw rotor pair where it is allowed to expand after ignition. The short direct connection gives low flow losses.

Huset för de två skruvrotorparen som är vatten-eller luftkylt, kan ha en eller två separata gavlar 8. Om huset görs i ett stycke med den vid kompressordelens utlopp/expanderdelens inlopp belägna gaveln uppnås fördelen att ingen packning erfordras för avtätning mot de relativt höga tryck som förekommer där.The housing for the two screw-rotor pairs which are water- or air-cooled, may have one or two separate ends 8. If the housing is made in one piece with the end located at the inlet of the compressor part / expander part, the advantage is obtained that no gasket is required for sealing against the relatively high pressures. which occurs there.

En ytterligare väsentlig fördel är att man därmed också undviker de godsansamlingar vid skarven som en separat gavel medför. Därigenom uppnås en effektivare kylning genom att kylkanalerna kan förläggas optimalt nära de partier som behöver god kylning. Gavlama innehåller de lager 9 och axeltätningar för lufi/ gas 10 och olja ll som erfordras.An additional significant advantage is that it thus also avoids the accumulations of goods at the joint that a separate gable entails. In this way, a more efficient cooling is achieved in that the cooling channels can be located optimally close to the portions that need good cooling. The ends contain the bearings 9 and shaft seals for lu fi / gas 10 and oil ll required.

Rotorema i de två skruvrotorparen är synkroniserade med varandra medelst kugghjiil 12, 13 för att undvika rotorkontakt. Expandem driver kompressom via kugghjulet 14 och dess effekt tas ut fiån en av dess malerotors 3 axeländar 15.The rotors in the two screw rotor pairs are synchronized with each other by means of gears 12, 13 to avoid rotor contact. The expander drives the compressor via the gear 14 and its power is taken from one of the shaft ends 15 of its grinding rotor 3.

De hjälpapparater som är nödvändiga för motoms funktion, tex. förgasare eller insprutningspump, etc, är inte visade.The auxiliary devices that are necessary for the function of the engine, e.g. carburetor or injection pump, etc., are not shown.
