INTEGRATED THROTTLING AND PRESSURE-RELIEF VALVE AND COMPRESSOR COMPRISING SAME

Title:

INTEGRATED THROTTLING AND PRESSURE-RELIEF VALVE AND COMPRESSOR COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2024/001519

Kind Code:

A1

Abstract:

An integrated throttling and pressure-relief valve, which is configured to connect to a high-pressure airflow channel (91) of a high-pressure housing of a compressor. The integrated throttling and pressure-relief valve comprises: a throttling portion (1), a pressure-relief portion (2), a connector, and a first seal (4), which is used for sealing the throttling and pressure-relief valve and the high-pressure airflow channel, wherein the throttling portion (1), the pressure-relief portion (2), the connector and the first seal (4) are connected in sequence. The throttling portion (1) is provided with a first airflow channel (100). The pressure-relief portion (2) is provided with a hollow cavity (21), which accommodates a piston (200) and an extensible structure (300) for driving the piston to perform a reciprocating motion; and at least one second airflow channel (400), which communicates the hollow cavity with the external space of the throttling and pressure-relief valve. When the piston is in a first state, the first airflow channel is not in communication with the hollow cavity; and when the piston is in a second state, the first airflow channel, the hollow cavity and the second airflow channel are in communication. In the integrated throttling and pressure-relief valve, a pressure-relief function and a throttling function are integrated into one component, thereby being able to reduce parts, save on space and lower the manufacturing cost. Further disclosed is a compressor comprising the throttling and pressure-relief valve.
