Abstract
The present disclosure provides a rotary device and a rotary system, to which a press-actuated gate valve mechanism is applied. In the rotary device and the rotary system, a pressure fluid chamber is disposed on an outside of a gate valve groove so that an action of a gate valve is controlled by means of a fluid pressure. Based on the rotary device and the rotary system, the present disclosure also provides a fluid motor, a compressor, a pump and a compressor corresponding to the rotary device and the rotary system.
Claims25
A rotary device with a press-actuated gate valve structure, comprising:
- a cylinder block which bounds a cylindrical inner chamber, is formed with a gate valve groove on an inside of the cylinder block along a direction of a central axis of the cylindrical inner chamber, and is formed with a pressure fluid chamber on an outside of the gate valve groove;
- a rotor assembly which forms an axially-extending sealed working space inside the cylindrical inner chamber by rotating in the cylindrical inner chamber;
- and
- a gate valve mounted outside the rotor assembly, so that at least a region of an upper surface of the gate valve or at least a region of an upper surface of an extension of the gate valve is exposed in the pressure fluid chamber and receives a force which is acted on the gate valve towards an inside of the cylinder block by a pressure fluid in the pressure fluid chamber,
- wherein the gate valve has an end pressed against an outer surface of the rotor assembly, and successively switches between a retracted state and a protruded state, so that the gate valve is retracted in the gate valve groove when in the retracted state, and the gate valve is protruded from the gate valve groove to partition the axially-extending sealed working space into two variable volume piston spaces, i.e., a first piston space A and a second piston space B, when in the protruded state.

A rotary system with a press-actuated gate valve structure, comprising:
- a cylinder block inner chamber partitioned into M cylindrical inner chambers, wherein a gate valve groove is formed at each of the M cylindrical inner chambers along a direction of a central axis of the cylinder block inner chamber, and a pressure fluid chamber is formed on an outside of each of the gate valve grooves;
- M rotor assemblies which are located in the corresponding cylindrical inner chambers, respectively, and which form axially-extending sealed working spaces by rotating in the corresponding cylindrical inner chambers;
- and
- M gate valves which are located outside the rotor assemblies in the corresponding cylindrical inner chambers, respectively, so that at least a region of an upper surface of each of the gate valves or at least a region of an upper surface of an extension of each of the gate valves is exposed in the corresponding pressure fluid chamber and receives a force which is acted on the each gate valve towards an inside of a cylinder block by a pressure fluid in the corresponding pressure fluid chamber, wherein M≥2, and in each cylinder block inner chamber, each of the gate valves has an end pressed against an outer surface of the corresponding rotor assembly, and successively switches between a retracted state and a protruded state, so that each of the gate valves is retracted in the corresponding gate valve groove when in the retracted state, and each of the gate valves is protruded from the corresponding gate valve groove to partition the corresponding axially-extending sealed working space into two variable volume piston spaces, i.e., a first piston space A and a second piston space B, when in the protruded state;
- and
- the M pressure fluid chambers are in communication with each other to form a sealed pressure fluid circulation path, and the M gate valves are configured in an interlocked drive relationship through the pressure fluid circulation path.
