| 提案されるのは吐出量を調整可能なベーンポンプ(VP)であって、前記ベーンポンプは、ポンプハウジング(G)と、前記ポンプハウジング内に配置されるカムリング(KR)と、前記ポンプハウジング内で回転可能に支承されるロータ(R)とを有する。前記ベーンポンプ(VP)は制御機構(RV)を有し、前記制御機構は移送される圧力媒体(DM)を貫流させかつ2つの出口(A1、A2)を有する。前記出口はそれぞれ2つの圧力室(DK1、DK2)の一方と結合されて、制御可能な割合の前記圧力媒体(DM)を前記圧力室に付加する。前記ロータ(R)に対する前記カムリング(KR)の偏心量を変更するために、前記2つの圧力室(DK1、DK2)は前記カムリング(KR)の外面に作用する。前記ベーンポンプ(VP)は、交差する2つの制御通路(STK*、STK#)を有し、前記制御通路はそれぞれ、前記出口(A1、A2)の一方を前記2つの圧力室(DK1、DK2)の一方と結合して、制御可能な割合の前記圧力媒体(DM)を前記圧力室に付加する。前記交差する制御通路(STK*、STK#)は主に前記ポンプハウジングのカバー(D’)内に、前記制御通路(STK*、STK#)が相互に接触することなく交差するように配置されている。この構造によって前記ベーンポンプ(VP)は、前記ロータの回転方向変更のため簡単に改造することができる。 | ||||||

| PROBLEM TO BE SOLVED: To provide a vehicular oil pump, driven by a rotation shaft in which a rotation direction when a vehicle goes forward is reversed to a rotation direction when the vehicle goes backward, capable of supplying oil whether the vehicle goes forward or backward, and having a simple structure.SOLUTION: When the vehicle goes forward, a first driven gear 168 drives a pump shaft 158 of the oil pump 120 via a first one-way clutch 166 to drive the oil pump 120. When the vehicle goes backward, a second driven gear 172 drives the pump shaft 158 of the oil pump 120 via a second one-way clutch 170 to drive the oil pump 120. By this, an oil-pressure requiring part of the vehicle can be supplied with the oil regardless of the travelling direction of the vehicle. In addition, as a special switching mechanism, etc., for switching an oil passage according to the travelling direction of the vehicle is not necessary, the device becomes simple, and manufacturing cost can be suppressed. | ||||||
| 66 | Internal gear pump for the brake system | JP2010530379 | 2008-09-22 | JP2011501034A | 2011-01-06 | アラーツェ ノルベルト; シェップ レネ |
| The invention relates to an internal gear pump for a braking system, in the pump housing of which an inner toothed hollow wheel and a gearwheel engaging in the toothing of the hollow wheel are mounted to rotate about parallel axes. The toothing thereof defines a tapering roughly crescent-shaped pump chamber, in which a filling piece is arranged supported along the length thereof. The circumferential surfaces of the filling piece closely correspond to the head diameter of the inner toothing of the hollow wheel or the gearwheel toothing and contact in a sealing manner with several tooth crowns covered thereby. A radial supporting force acts over a longitudinal range of the filling piece for improved sealing of a circumferential surface of the filling piece against the tooth crowns supporting the circumferential surface. According to the invention, a loose fit is provided between the circumferential surfaces of the filling piece and the opposing tooth crowns of the hollow wheel and gearwheel and the play acting on the filling piece is partly eliminated by support forces acting in opposing radial directions which act on the filling piece at a distance from each other. | ||||||

| PROBLEM TO BE SOLVED: To provide a double-rotating vane hydraulic motor capable of easily changing the rotating direction of an output shaft (main spindle) without replacing a part. SOLUTION: This motor has a rotor 30 mounted with a vane 35, which is rotatably housed in a cam casing 10, first and second ports 13 and 15 which serve as input and output ports for supplying and discharging a working fluid to the rotor 30, and a bypass passage 80 for carrying out the working fluid from the bearing parts 51 and 61 of the main spindle 70 of the rotor 30. This motor further has a drain port 17 for discharging the working fluid to the outside in addition to the first and second ports 13 and 15. The drain port 17 is allowed to communicate with the bypass passage 80, so that the working fluid carried out from the bearing parts 51 and 61 is discharged out through the drain port 17.

| The invention proposes a vane pump (VP) with adjustable delivery volume, which vane pump has a pump housing (G), a cam ring (KR) arranged therein, and a rotor (R) which is rotatably movably mounted therein. The vane pump (VP) has a regulating device (RV) through which the delivered pressure medium (DM) flows and which has two outlets (A1, A2) which are each connected to one of two pressure chambers (DK1, DK2) in order to charge these with regulable proportions of the pressure medium (DM), wherein, to change the eccentricity of the cam ring (KR) relative to the rotor (R), the two pressure chambers (DK1, DK2) act on the outer surface of the cam ring (KR). The vane pump (VP) has two criss-crossing control ducts (STK*, STK#) which connect in each case one of the outlets (A1, A2) to one of the two pressure chambers (DK1, DK2) in order to charge these with the regulable proportions of the pressure medium (DM). The criss-crossing control ducts (STK*, STK#) are preferably arranged in a cover (D′) of the pump housing such that the control ducts (STK*, STK#) are in a criss-crossing arrangement without coming into contact with one another. By means of this design, the vane pump (VP) can be easily reconfigured for a change in rotational direction of the rotor. | ||||||
