| 摘要 | A combined motor and rotary fluid device including a fluid unit having a housing and a rotor within said housing, motor means, and a mounting structure for mounting said fluid unit relative to said motor means including a plurality of posts extending outwardly from said motor for supporting rings clamping a resilient diaphragm therebetween on which said fluid unit housing is mounted, and a shaft extending outwardly from said motor for mounting the rotor of said fluid unit, said resilient diaphragm permitting a floating movement of said housing. | ||||||
| 权利要求 | 1. A combined motor and rotary fluid device comprising a fluid unit including a housing and a rotor mounted in sealing relationship relative to said housing, motor means, mounting means for mounting said fluid unit relative to said motor means to permit limited floating movement of said fluid unit during rotation of said rotor to therby provide good sealing contact between said rotor and said housing without binding, said motor means including shaft means and wherein said rotor is mounted on said shaft means and wherein said mounting means resiliently mount said housing relative to said motor means, said mounting means comprising a resilient diaphragm having a first portion secured to said motor means and a second portion secured to said housing, and a resilient portion between said first and second portions. 2. A combined motor and rotary fluid device as set forth in claim 1 including adjustment means for permitting selective limited radial movement of said housing during the mounting of said housing on said motor means, to thereby adjust the relative positions of said rotor and said housing. 3. A combined motor and rotary fluid device as set forth in claim 2 wherein said adjustment means comprise elongated slots in said first portion, fastener means extending through said elongated slots to permit radial movement of said resilient diaphragm when said fastener means are in a loosened condition but which clamp said first portion of said diaphragm to said motor means when said fastener means are in a tightened condition. 4. A combined motor and rotary fluid device as set forth in claim 3 including a second elongated slot in said housing through which said shaft means extends for permitting said radial movement of said housing. 5. A combined motor and rotary fluid device comprising a fluid unit including a housing and a rotor mounted in sealing relationship relative to said housing, motor means, mounting means for mounting said fluid unit relative to said motor means to permit limited floating movement of said fluid unit during rotation of said rotor to thereby provide good sealing contact between said rotor and said housing without binding, said motor means including shaft means and wherein said rotor is mounted on said shaft means, and wherein said mounting means comprise first means on said moTor means and second means on said housing for effecting sliding movement relative to said first means in a direction substantially axially of said shaft means during operation of said motor means. 6. A combined motor and rotary fluid device as set forth in claim 5 wherein said first means comprise a plurality of substantially parallel pins extending from said motor means in a direction substantially axially of said shaft means, and wherein said second means comprise means including a plurality of bores effectively located in said housing for receiving said pins with a sliding fit. 7. A combined motor and rotary fluid device as set forth in claim 6 wherein said second means comprise resilient members on said housing for permitting limited radial movement of said housing relative to said shaft means. 8. A combined motor and rotary fluid device as set forth in claim 7 wherein said resilient members comprise lobe-like members secured to and extending outwardly from said housing. 9. A combined motor and rotary fluid device comprising a fluid unit including a housing and a rotor mounted in sealing relationship relative to said housing, motor means, mounting means for mounting said fluid unit relative to said motor means to permit limited floating movement of said fluid unit during rotation of said rotor to thereby provide good sealing contact between said rotor and said housing without binding, said motor means including shaft means and wherein said rotor is mounted on said shaft means and wherein said mounting means resiliently mount said housing relative to said motor means, said mounting means comprising a cup-like member secured to said motor means and wherein said housing is positioned within said cup-like member, and a filling of resilient material within said cup-like member for supporting said housing. |
