Abstract
According to one embodiment of the invention, a gerotor apparatus includes a first gerotor, a second gerotor, and a synchronizing system operable to synchronize a rotation of the first gerotor with a rotation of the second gerotor. The synchronizing system includes a earn plate coupled to the first gerotor, wherein the cam plate includes a plurality of cams, and an alignment plate coupled to the second gerotor. The alignment plate includes at least one alignment member, wherein the plurality of cams and the at least one alignment member interact to synchronize a rotation of the first gerotor with a rotation of the second gerotor.
Claims18
A gerotor apparatus, comprising:
- a housing;
- a rotatable outer gerotor disposed at least partially within the housing, the outer gerotor at least partially defining an outer gerotor chamber;
- a rotatable inner gerotor disposed at least partially within the outer gerotor chamber;
- a seal formed between the housing and at least one of the outer gerotor and the inner gerotor, wherein the seal is configured to restrict passage of fluid between the housing and the at least one of the outer gerotor and the inner gerotor;
- a seal portion of the housing;
- and
- one or more seal protrusions coupled to the at least one of the outer gerotor and the inner gerotor, the one or more seal protrusions configured to contact the seal portion.
A gerotor apparatus, comprising:
- a housing;
- an outer gerotor disposed at least partially within the housing, the outer gerotor at least partially defining an outer gerotor chamber;
- an inner gerotor disposed at least partially within the outer gerotor chamber;
- a seal formed between the housing and the outer gerotor, the seal operable to restrict the passage of fluid between the outer gerotor chamber and a region outside the outer gerotor chamber;
- a seal portion of the housing;
- and
- one or more seal protrusions coupled to the at least one of the outer gerotor and the inner gerotor, the one or more seal protrusions configured to contact the seal portion.
A gerotor apparatus, comprising:
- a housing;
- an outer gerotor disposed at least partially within the housing, the outer gerotor at least partially defining an outer gerotor chamber;
- an inner gerotor disposed at least partially within the outer gerotor chamber;
- and
- a labyrinthian seal formed between the housing and the outer gerotor, the labyrinthian seal operable to restrict the passage of fluid between the outer gerotor chamber and a region outside the outer gerotor chamber, the labyrinthian seal formed by one or more seal protrusions coupled to the at least one of the outer gerotor and the inner gerotor coming into contact with a seal portion of the housing.
