Abstract
The invention discloses a brake master cylinder with a center valve and with an oil intake receiver on the side edge of an oil intake bolt. The brake master cylinder comprises a cylinder body, wherein a protective cover is mounted at the right end of the cylinder body; an oil chamber is arranged at the middle part of the cylinder body; a piston assembly is mounted at the right end of the oil chamber; a control lever is mounted at the right end of the piston assembly; a spring seat is mounted at the left end of the piston assembly; an oil intake vale core is mounted at the left end of the spring seat; a spring is mounted outside the oil intake valve core; an oil intake vale seat is mounted at the left end of the oil intake valve core; an oil intake valve spring and a valve leather ring are mounted in the oil intake valve seat; the left end of the oil intake valve seat pops against the inner wall of the cylinder body; an oil inlet is arranged on the cylinder body at the upper end of the oil intake valve seat, the oil intake bolt is mounted in the oil inlet, and the oil intake receiver is mounted on the side edge of the oil intake bolt; an oil delivery joint is arranged at the side edge of the left end of the cylinder body; and a dust-proof cork is mounted outside the oil delivery joint. According to the invention, by mounting the transverse oil intake receiver on the side edge of the oil intake bolt, dust and solid impurities can be effectively prevented from easily entering the cylinder body with braking oil and rubbing the piston and the valve, and therefore the whole service life of the product is improved.
