Abstract
An improved quick release coupling is provided. The quick release coupling enables higher fluid flow rates and lower pressure drops. The quick release coupling is configured to be a connection and disconnection under high pressure conditions on one or both of the male and the female sides of the coupling. The quick release coupling enables intentional manual disconnection as well as breakaway disconnection under high working pressures.
Claims17
A coupling comprising:
- a coupling body defining a generally cylindrical inner cavity including a first end portion and a second end portion;
- a socket body including a first end portion and a second end portion, the first end portion of the socket body coaxially positioned within the first end portion of the coupling body, the socket body configured to slide axially relative to the coupling body;
- a piston including a first end portion and a second end portion, the first end portion being coaxially positioned within the second end portion of the socket body, the piston configured to slide axially relative to the socket body as well as the coupling body;
- a poppet including a first end portion and a second end portion, the first end portion of the poppet coaxially positioned within and abutting the first end portion of the piston, the poppet configured to slide axially relative to the piston;
- and
- a poppet pin including a first end portion and a second end portion, the poppet pin coaxially positioned within the poppet, the poppet pin configured to slide axially relative to the poppet.

A method of connecting a male coupling to a female coupling including the steps of:
- pushing a male coupling into a female coupling and driving a piston and poppet assembly in the female coupling rearward to cause a locking mechanism to lock the male coupling to the female coupling;
- and
- energizing a pump to drive hydraulic fluid into the female coupling and drive the piston forwardly, which drives a poppet of the male coupling rearward to open a primary flow path that extends form the female coupling to the male coupling.
A coupling comprising:
- a coupling body defining a generally cylindrical inner cavity including a first end portion and a second end portion;
- a socket body including a first end portion and a second end portion, the first end portion of the socket body coaxially positioned within the first end portion of the coupling body, the socket body configured to slide axially relative to the coupling body;
- a piston including a first end portion and a second end portion, the first end portion being coaxially positioned within the second end portion of the socket body, the piston configured to slide axially relative to the socket body as well as the coupling body;
- a poppet including a first end portion and a second end portion, the first end portion of the poppet coaxially positioned within and abutting the first end portion of the piston, the poppet configured to slide axially relative to the piston;
- and
- a poppet pin including a first end portion and a second end portion, the poppet pin coaxially positioned within the poppet, the poppet pin configured to slide axially relative to the poppet.
