Claims (1)
を具備し、該燃料貯留室を一方では燃料貯留室内に向け
てのみ流通可能な第１の逆止弁を介して気化器フロート
室内に連結すると共に他方では燃料貯留室からの洗出の
みを許容する第２の逆止弁を介して気化器吸気通路内に
連結し、上記負圧室を負圧導管を介して気化器スロット
ル弁後流の吸気通路内に連結し、該負圧導管を大気圧が
低くなるにつれて大気開口面積が減少する大気連通制御
弁に連結した補助加速ポンプにおいて、上記負圧導管と
大気連通制御弁間に固定絞りを挿入して該固定絞りのみ
によって大気連通制御弁から負圧導管に向かう空気流を
制御するようにした補助加速ポンプの高度補償装置。It comprises a fuel storage chamber and a negative pressure chamber separated by a diaphragm, and the fuel storage chamber is connected to the carburetor float chamber via a first check valve that allows flow only toward the fuel storage chamber. and, on the other hand, into the carburetor intake passage via a second check valve which only allows flushing out of the fuel storage chamber, and connects said negative pressure chamber to the carburetor throttle valve downstream of the carburetor throttle valve via a negative pressure conduit. In an auxiliary acceleration pump that is connected to an intake passage and the negative pressure conduit is connected to an atmospheric communication control valve whose opening area to the atmosphere decreases as atmospheric pressure decreases, a fixed throttle is provided between the negative pressure conduit and the atmospheric communication control valve. An altitude compensation device for an auxiliary accelerator pump, which is inserted so that the air flow from the atmospheric communication control valve to the negative pressure conduit is controlled only by the fixed throttle.
