The present invention relates to a washer pump for a vehicle. A first nozzle (130) and a second nozzle (140) comprise: a first nozzle housing (131) and a second nozzle housing (141) which are coupled to each other in an airtight manner at both sides of a membrane (150); a first connector (132) and a second connector (142) provided on one side of the first nozzle housing (131) and the second nozzle housing (141), respectively, and coupled to a first outlet (111) and a second outlet (112); a first supply port (133) and a second supply port (143) which are spaced apart from both sides of the membrane (150) in deep parts of the first nozzle housing (131) and the second nozzle housing (141), respectively, and are provided in a tubular shape to be symmetrical to each other. The membrane (150) comprises: a fixing part (151) interposed between the first nozzle housing (131) and the second nozzle housing (141) in an airtight manner and configured to fix the first nozzle housing (131) and the second nozzle housing (141); a flow part (152) formed to have a thickness smaller than a thickness of the fixed part (151) and configured to flow according to the hydraulic pressure of a washer fluid; and a closing part (153) formed in a disk shape corresponding to a diameter of the first supply port (133) and the second supply port (143) and protruding so that both sides thereof are symmetrical to each other. Accordingly, compared to a conventional case, the washer pump has an improved ease of assembly and operation performance.
본 발명은 차량용 워셔펌프에 관한 발명으로, 제1노즐(130) 및 제2노즐(140)은, 멤브레인(150)의 양측에서 상호 기밀하게 결합하는 제1노즐하우징(131) 및 제2노즐하우징(141)과, 제1노즐하우징(131) 및 제2노즐하우징(141) 각각의 일측에 구비하여 제1토출구(111) 및 제2토출구(112)에 결합하는 제1연결구(132) 및 제2연결구(142)와, 제1노즐하우징(131) 및 제2노즐하우징(141) 각각의 심부에서 멤브레인(150)의 양측으로부터 이격하되 상호 대칭하도록 관체 형상으로 마련하는 제1공급구(133) 및 제2공급구(143)를 구비하고, 멤브레인(150)은, 제1노즐하우징(131)과 제2노즐하우징(141) 사이에 기밀하게 개재하여 고정하는 고정부(151)와, 고정부(151)의 두께보다 얇은 두께로 형성하여 워셔액의 유압에 따라 유동하는 유동부(152)와, 제1공급구(133) 및 제2공급구(143)의 관경에 상응하는 원반상으로 형성하여 양측이 상호 대칭하도록 돌출하는 폐쇄부(153)로 구성함으로써 종래에 비해 조립성 및 작동성능이 향상된 워셔펌프를 제공하는 것이 특징이다.
