関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is a distributing valve for an internal-shaft hydraulic rotary piston machine, such as a motor, with a meshing part, in which a rotary slide valve rotated by the main shaft connects a supply part and a discharge part. two annular grooves connected to each other and alternating successive supply and discharge distribution grooves starting from both annular grooves and extending transversely thereto; are of the type that are fixed to the casing and each cooperate with a control opening opening into a displacement chamber.
このような形式の公知の分配弁は、回転すべり弁スリー
ブの外周に軸方向にずらされた２つの環状みぞと、該環
状みぞに垂直に接続する軸方向に向いた分配みぞとを有
している（ドイツ連邦共和国特許出願公告第１５５３０
０４号明細書）。Known distribution valves of this type have two axially offset annular grooves on the outer circumference of the rotary slide valve sleeve and an axially oriented distribution groove that connects perpendicularly to the annular grooves. (Federal Republic of Germany Patent Application Publication No. 15530)
04 Specification).
このような分配弁を備えた回転ピストン機械を作動させ
ると、この回転ピストン機械が上方回転数範囲で作動す
るぱあいに回転ピストン機械の効率は低下する。When operating a rotary piston machine with such a distributor valve, the efficiency of the rotary piston machine decreases as long as the rotary piston machine operates in the upper rotational speed range.
このことは、液圧式回転ピストン機械がきわめて小さい
全体寸法を有するぱあいに、たとえば長さが去った１０
ｃｍで直径がたった６ｃｍであるケーシングのぱあいに
とりわけ当てはまる。This means that hydraulic rotary piston machines have extremely small overall dimensions, e.g.
This applies in particular to the casing gap, which has a diameter of only 6 cm.
さらに、円板状の公知の回転すべり弁のぱあいには、半
径方向に延びる分配みぞが交互に内側環状みぞ及び外側
環状みぞと接続する。Furthermore, in the gap of the known disc-shaped rotary slide valve, radially extending distribution grooves alternately connect with inner and outer annular grooves.
このぱあい、前記の欠点が当てはまる。In this case, the above-mentioned drawbacks apply.
さらに公知のものは（ドイツ連邦共和国特許出願公開第
２６０８８８７号明細書）、分配みぞが回転すベリ弁ケ
ーシングの外側において、正確に軸平行ではなく、軸方
向に対して３〜８°のわずかな角度を成して延びている
。Furthermore, in the known case (German Published Patent Application No. 2,608,887), the distribution groove is not exactly parallel to the axis on the outside of the rotating Veri valve casing, but is slightly parallel to the axis at an angle of 3 to 8°. It extends at an angle.
このような形式でそれぞれの分配みぞは、やはり軸方向
に延びる制御開口と徐々に接続することができ、従って
圧力衝撃が排除される。In this way, each distribution channel can be connected gradually with a control opening that also extends in the axial direction, thus eliminating pressure shocks.
本発明の課題は、とりわけ上方回転数範囲でかつ寸法が
きわめて小さいぱあいに液圧式回転ピストン機械の効率
が改良されるような前述の形式の分配弁を提供すること
である。The object of the invention is to provide a distributor valve of the above-mentioned type, with which the efficiency of hydraulic rotary piston machines is improved, especially in the upper rotational speed range and in very small dimensions.

と接続しているようにしたこのような形式により、供給
分配みぞ内に流入する液体のために回転羽根効果あるい
は変向効果が与えられ、このような効果が流れを全部改
良する。In order to solve this problem, in the configuration of the present invention, each supply distribution groove 24 has an inclined inflow cross section 31.
This type of connection with the annular groove 26 at a location offset in the direction of rotation D through the groove provides a rotating vane effect or deflection effect for the liquid flowing into the supply distribution groove. This effect improves the overall flow.
変向損失が減少されかつみぞの充てん度が高められる。Turning losses are reduced and groove filling is increased.
このような構成は、高い回転数のぱあいにとりわけ効果
がある。Such an arrangement is particularly effective in high rotational speed ranges.
これはここで述べられた回転ピストン機械は低速回転体
としてみなされるけれども、しかしそれにもかかわらず
きわめて高い圧力流体流過部を有しているからである。This is because the rotary piston machine described here is considered a low speed rotor, but nevertheless has a very high pressure fluid flow.
この効果はきわめて小さい寸法の機械のぱあいにも達成
される。This effect is achieved even in machine gaps of extremely small dimensions.
これはスペースの状態のためみぞが、相応する高い流れ
抵抗を有する相応する小さい流れ横断面を有しているか
らである。This is because, due to the space conditions, the channels have a correspondingly small flow cross section with a correspondingly high flow resistance.
有利には、それぞれの排出分配みぞ２５が、傾斜する流
出横断面３２を介して環状みぞ２７の、回転方向Ｄとは
逆にずらされた個所と接続している。Advantageously, each discharge distribution groove 25 is connected via an inclined outlet cross section 32 to a location of the annular groove 27 that is offset against the direction of rotation D.
このばあい流出範囲でも流入範囲と同じ利点が得られる
。In this case, the same advantages are obtained in the outflow region as in the inflow region.
さらにこのような機械は、前述と同じ作用効果を有する
モータあるいはポンプとして同じ回転方向で運転され、
このばあい流入横断面と流出横断面とがその機能を交換
するだけでよい。Furthermore, such a machine can be operated in the same direction of rotation as a motor or pump with the same effect as described above,
In this case, the inlet and outlet cross sections need only exchange their functions.
さらに傾胴する横断面が、湾曲状に経過することができ
る。Furthermore, the tilting cross section can have a curved course.
このことによって変向範囲において申し分ない流れが得
られる。This results in a perfect flow in the deflection range.
