Description

 The invention relates to the field of energy, transport, mechanical engineering and can be used as a compressor pump, hydraulic motor, etc. Known rotary-blade device for transmitting and converting energy (see UK patent N 795898, CL 110 (2), publ. 1958).

 The closest analogue is a rotor-blade energy conversion device, including a housing with an annular channel with inlet and outlet windows, a rotor with symmetrically arranged blades, a cylinder-shaped bypass valve with a side cavity, and a kinematic coupling mechanism (see German application N 2432781, cl. F 01 C 1/12, publ. 1976).

 The rotor-blade energy transmission and conversion device includes a housing with an annular channel with inlet and outlet windows, a rotor with symmetrically arranged blades, a cylinder-shaped bypass valve with a side cavity, and a kinematic coupling mechanism. The device is characterized in that the annular channel is made with an annular gap through which the blades, in shape corresponding to the cross section of the annular channel, are connected to the rotor. The bypass valve is made internal relative to the annular channel. The ratio of rotation of the bypass valve and the rotor is 2: 1.

 Achievable technical result is to ensure simplicity, compactness and reliability in the operation of the rotor-blade device.

 The rotor-blade device for transmitting and converting energy (Fig. 1, 2) consists of a housing 1 with an annular channel 2, a rotor 3 with two symmetrically located blades 4, 5, an overflow valve 6 and a kinematic coupling mechanism 7.

 The annular channel 2 serves to move the working fluid and can have a different cross section. In the side wall of the annular channel adjacent to the housing 1, there is an annular gap 8 through which the blades are connected to the rotor 3. The annular channel is provided with windows for the inlet 9 and the outlet 10 of the working fluid. The rotor blades in shape and size exactly correspond to the cross section of the annular channel and serve to move the working fluid inside it or transmit torque to the rotor shaft under the influence of the working fluid.

 The bypass valve 6, without creating obstacles to the movement of the rotor blades, overlaps the annular channel 2 and forces the working fluid to flow from the inlet to the outlet in a certain direction. The valve has the shape of a cylinder with a side cavity and is installed in socket 11. Prevention of the overflow of the working fluid through the installation site of the bypass valve for any angular deviations is ensured by the fact that the distance between the holes of the annular channel with the socket 11 is greater than the distance between the edges of the cavity of the bypass valve.

 The bypass valve in its position relative to the annular channel can be both internal (Fig. 1) and external (Fig. 2).

 The kinematic communication mechanism 7 provides synchronous in a certain ratio and direction mutual rotation of the bypass valve and the rotor.

 One-way rotation is carried out with the internal location of the bypass valve - gears with internal gearing of the teeth (Fig. 1, 4, 5, 6, 10). The opposite rotation is carried out with the external location of the bypass valve - gears with external gearing of the teeth (Fig. 2, 7, 8, 9, 11). In the proposed RLUPPE, the ratio of rotation of the bypass valve and the rotor is taken as 2: 1.

 The RULPE working cycle is carried out in one revolution of the rotor and is divided into the phase of the working stroke and the bypass phase. In accordance with this, the annular channel is also divided into sections of the stroke and bypass. The structure of the working stroke section includes the inlet and outlet windows and part of the annular channel between them.

 The operation of RULPE is considered on the example of the blade 4, given that the blade 5 performs identical work.

1. The working stroke when moving the working fluid (Fig. 1):
- when the rotor 3 is rotated, the blade 4 is set in motion and moves the working fluid located in the annular channel 2 (in the direction of the window 10), which, upon encountering the bypass valve, is forced out by the blade from the annular channel through the exhaust window 10;
- under the action of a rarefaction force through the inlet window 9 into the working section of the annular channel 2, after the blade 4, a new part of the working fluid penetrates.

2. The stroke when transmitting torque to the rotor shaft under the influence of the working fluid (Fig. 1):
- the working fluid under pressure penetrates into the working section of the channel 2 through the inlet window 9 and presses on the blade 4, which moves in the direction of the outlet window 10, rotating the rotor 3;
- the working fluid after passing through the blade 4 of the inlet window 10 flows through it from the annular channel 2.

3. Bypass (Fig. 4 - 9):
- at the moment of approaching the blade 4 to the socket 11, the bypass valve 6 rotates towards it with its cavity (Fig. 4, 7);
- the blade 4 enters the cavity of the bypass valve, which rotates and frees up space for further advancement of the blade (Fig. 5 - 9).

 This duty cycle can be defined as the pump cycle, and the annular channel, where it is carried out, designated as the working section. The annular channel can be made with any number of working sections, in turn, the working sections in the same RULPE can be different in length of the sections of the working stroke.

 The same design can work both in the mode of moving the working fluid, and in the mode of transmitting torque to the rotor shaft under the influence of the working fluid.

 The ratio of the number of rotor blades and bypass valves, taken 2: 1, ensures constant overlapping of the annular channel by the blades between the inlet and outlet windows, at any angular position of the rotor, which prevents spontaneous movement of the working fluid (between the inlet and outlet windows).
