Abstract
A check valve is disclosed. The check valve, which is installed in a modulator block of a brake system having a flow path forming a hydraulic circuit, may include: a sleeve housing whose both ends open, the sleeve housing having a discharge flow path, wherein at least one outlet is formed in the discharge flow path; a pair of adaptors respectively coupled with both open ends of the sleeve housing, wherein in one end of each adaptor, an inlet connected to a flow path of the modulator block is formed, and in the other end of the adaptor, a valve seat connected to the discharge flow path is formed; an elastic member disposed in the discharge flow path; and a pair of opening and closing members respectively supported on both ends of the elastic member, and disposed to selectively contact each valve seat of the pair of adaptors.

A check valve installed in a modulator block of a brake system having a flow path forming a hydraulic circuit, the check valve comprising:
- a sleeve housing whose both ends open, the sleeve housing having a discharge flow path, wherein at least one outlet is formed in the discharge flow path;
- a pair of adaptors respectively coupled with both open ends of the sleeve housing, wherein in one end of each adaptor, an inlet connected to a flow path of the modulator block is formed, and in the other end of the adaptor, a valve seat connected to the discharge flow path is formed;
- an elastic member disposed in the discharge flow path;
- and
- a pair of opening and closing members respectively supported on both ends of the elastic member, and disposed to selectively contact each valve seat of the pair of adaptors.
A check valve installed in a modulator block of a brake system having a flow path forming a hydraulic circuit, the check valve comprising,
- a pair of opening and closing members configured to selectively open and close a pair of orifices communicating a pair of inlets connected to a flow path of the hydraulic circuit with a discharge flow path located between the pair of inlets,
- wherein the pair of opening and closing members are elastically supported on both ends of a coil spring to close the corresponding orifices, move by a pressure of oil entered through the corresponding inlets to open the corresponding orifices, and close the corresponding orifices by an elastic force of the coil spring when the pressure of the oil is removed.
A check valve comprising:
- a sleeve housing having a body whose both ends open, the body having a hollow discharge flow path, wherein at least one outlet is formed along an outer circumference of the body;
- a pair of adaptors coupled with both open ends of the sleeve housing, each of the pair of adaptors having an inlet through which oil enters and an orifice communicating with the discharge flow path;
- and
- a pair of opening and closing members respectively supported on both ends of the elastic member accommodated in the inside of the body, and configured to selectively open and close each orifice of the pair of adaptors.
