Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] like Figure 1 to Figure 3 As shown, a steady flow valve for a pump in this embodiment includes a valve body 1, an oil inlet 2 (P) and an oil return port 3 (T) arranged in the valve body 1, and the valve body 1 is also provided with The steady-flow spring chamber 4 and the output oil passage 5 are both connected to the oil inlet 2. The steady-flow valve core 6 slides in the steady-flow spring chamber 4. The steady-flow valve core 6 is provided with a piston section 6a, and the piston section 6a It is located between the oil return port 2 and the oil inlet port 3; on the valve body 1 behind the steady flow valve core 6, a steady flow valve seat 7 is threaded, and between the steady flow valve core and the 6 steady flow valve seat 7 There is a return spring 8 between them, and the three form a pressure relief valve 20; an orifice 9 (S) is provided in th...
