Reciprocating switch for high-pressure fluid lines

A reciprocating switch for high-pressure fluid lines comprising at least:

• an inlet switch body, one end of which has an inlet and other end of which is a closed end, an inlet chamber communicating with the inlet being formed between the inlet and the closed end, and the inlet being used to connect and communicate with a fluid supply component;
• an outlet switch body, extending outwardly from the closed end of the inlet switch body and featuring an outlet at its outer end, an outlet chamber communicating with the outlet being formed between the outlet and the closed end, and the outlet being used to connect and communicate with a fluid-driven device;
• a first communication port, formed by at least one aperture near the closed end penetrating the inlet switch body, and used to communicate the inlet chamber with an exterior of the inlet switch body;
• a second communication port, formed by at least one aperture near the closed end penetrating the outlet switch body, and used to communicate the outlet chamber with an exterior of the outlet switch body;
• and
• a sleeve, having inner edge shapes at both ends corresponding to outer edge shapes of the inlet switch body and the outlet switch body, allowing the sleeve to fit and slide over outer surfaces of the inlet switch body and the outlet switch body between a first position and a second position, and inner wall of the sleeve having an annular groove in a middle section;
• wherein,
• inner wall surfaces at the both ends of the sleeve abut against the outer surfaces of the inlet switch body and the outlet switch body, respectively;
• when the sleeve is in the first position, the both ends of the sleeve encircle the first communication port and the second communication port, but the annular groove communicates the first communication port and the second communication port, allowing fluid to enter through the inlet and flow out from the outlet;
• and
• when the sleeve is in the second position, the both ends of the sleeve encircle the first communication port but do not encircle the second communication port, thereby preventing the annular groove from communicating with the second communication port, allowing the fluid to enter through the inlet but not flow out of the outlet.
