Claims (9)

1. Skruekompressor (2), primært til gasholdige kølemidler, hvilken skruekompressor omfatter et kompressorhus (4), der omfatter en lian- (8) og en hunskruerotor (10), som er arrangeret i skruerotorudboringer (6) i kompressorhuset (4), hvilke han- (8) og hunrotorer (10) er samroterende drivbare og samvirker til at komprimere kølemidlet, hvor kompressorhuset er forbundet med et lejehus (14), hvor rotorendeplader (16,18) er placeret mellem skruerotorerne (8,10) og lejehuset (14), hvilke rotorendeplader omfatter udskæringer for afgangsporte (20,22), kendetegnet ved, at endeplademe omfatter yderdiametre, hvilke diametre betydeligt overskrider de tilsvarende rotordiametre, og hvilke yderdiametre af endeplademe samvirker med recesser i kompressorhuset og med recesser i lejehuset.
2. Skruekompressor ifølge krav 1, kendetegnet ved, at den første og den anden endeplade omfatter oliekanaler til at føre olie mod deres indre udboringer, hvor spillerummet mod rotorakslen frembringer en begrænset oliestrøm til at smøre rotorlejerne ved kompressorens afgangsende.
3. Skruekompressor ifølge krav 1 eller 2, kendetegnet ved, at den første og den anden endeplade omfatter oliekanaler til at føre olie mod deres indre udboringer, hvor spillerummet mod rotorakslen frembringer en begrænset oliestrøm til at tætne de ak-sielle spillerum mellem rotorerne og endeplademe,
4. Skruekompressor ifølge ethvert af krav 1-3, kendetegnet ved, at rotorendepla-derne skal udformes med cirkulære recesser omkring deres centrale åbninger for at tillade en oliefilm at fa adgang til lejernes inderside.
5. Skruekompressor ifølge ethvert af krav 1 - 4, kendetegnet ved, at der er udformet labyrinttætninger mellem den indre åbning i endeplademe og rotoraksleme.
6. Skruekompressor ifølge ethvert af krav 1-5, kendetegnet ved, at endeplademe omfatter et antal oliekanaler for fordeling af olie indvendigt i kompressoren.
7. Skraekompressor ifølge ethvert af krav 1-6, kendetegnet ved, at mindst en af endeplademe omfatter mindst en udboring, som er forbundet med oliekanaler, hvor mindst en udboring omfatter en tiykstyringsventil.
8. Skruekompressor ifølge ethvert af krav 1 - 7, kendetegnet ved, at mindst en af endeplademe omfatter kanaler, som er forbundet med en economiser port, hvilken port er forbundet med et middeltryk i kølesystemet, hvor kølemiddel ved middeltryk flyder gennem kanaler i mindst en af endeplademe mod et indløb, og hvor der er et lavt eller middel trykniveau i kompressoren.
9. Skruekompressor ifølge ethvert af krav 1 - 8, kendetegnet ved, at mindst en af endeplademe omfatter kanaler, som er forbundet med en højtryksvæskeindsprøjt-ningsport.
