Abstract
A rotary pump may include a rotary cover and a rotary housing that may be engaged with one another during operation. A ring gear may be positioned within an internal portion of the rotary cover and rotary housing, and an inner gear may be positioned within a portion of the ring gear. The rotary pump may be configured with a pressure relief portion that may be in fluid communication with an outlet of the pump. The rotary pump may be configured such that pressurized fluid passing through the pressure relief portion is routed to an inlet of the rotary pump.
Claims10
A rotary pump comprising:
- a. a rotary housing configured for selective engagement with an engine, said rotary housing comprising:
- i. an outlet cavity formed in an interior of said rotary housing;
- ii. an outlet in fluid communication with said outlet cavity;
- iii. a pressure relief portion in fluid communication with said outlet cavity;
- iv. a pressure relief discharge in fluid communication with said pressure relief portion;
- v. a pressure relief cavity formed in an interior of said rotary housing, wherein said pressure relief cavity is in fluid communication with said pressure relief discharge;
- vi. a return channel in fluid communication with said pressure relief cavity;
- vii. an inlet in fluid communication with said return channel;
- b. a ring gear positioned in said interior of said rotary housing;
- c. an inner gear positioned within said ring gear;
- and,
- d. a rotary cover that is selectively engageable with said rotary housing so as to cover said interior of said rotary housing.
A pump comprising:
- a. a main body having a gear chamber formed therein, wherein said main body is formed with an outlet port and a pump outlet passage fluidly connecting said gear chamber to said pump outlet port, and wherein said main body includes an inlet channel in fluid communication with said gear chamber;
- b. a drive gear positioned in said main body;
- c. an idler gear positioned in said main body;
- d. a pressure relief assembly in fluid communication with said pump outlet passage, wherein said pressure relief assembly includes a pressure relief outlet;
- and,
- e. a return channel fluidly connecting said pressure relief outlet to said inlet channel.
A method of increasing the efficiency of a pump, said method comprising:
- a. outfitting said pump with a pressure relief portion, wherein said pressure relief portion is in fluid communication with an outlet of said pump;
- and,
- b. providing a return channel to fluidly connect a pressure relief discharge of said pressure relief portion with an inlet of said pump.
