Flow path control device and vehicle height adjustment apparatus

Abstract

The invention provides a first switching valve, a unit body and a control valve. The first switching valve opens and closes a first radial communicating hole which is aligned for supplying oil to a storing chamber. Theunit body is provided with an accommodating part, the first radial communication hole and a side recessed part. The accommodating part recesses from a first switching valve backpressure chamber which accommodates the oil that applies a force in a direction of closing the first switching valve. The first radial communicating hole is communicated with the accommodating part and the storing chamber. The side recessed part recesses from the first switching valve backpressure chamber for connecting with the accommodating part and is not connected with the first radial communicating hole. The unit body forms a discharging flowing path. The discharging flowing path is aligned in a manner of penetrating the first radial communicating hole and the side recessed part from the first switching valve backpressure chamber to the storing chamber. The control valve is provided with a trough. The control valve is assembled to the accommodating part of the unit body. The control valve opens and closes the discharging flowing path through movement between a position where the trough is communicated with the side recessed part and the first radial communicating hole and a position wherein the trough is not communicated with the side recessed part and the first radial communicating hole.

Description

technical field [0001] The present invention relates to a flow path control device and a vehicle height adjusting device which adjusts a vehicle height of a motorcycle. Background technique [0002] In recent years, there has been proposed an apparatus that increases the vehicle height of a motorcycle while running and lowers the vehicle height when stopped so that a driver can easily get on and off the motorcycle. [0003] For example, a vehicle height adjusting device disclosed in JP-B-H08-22680 automatically changes the vehicle height of the motorcycle in response to the vehicle speed of the motorcycle. The vehicle height adjusting device automatically raises the vehicle height when the vehicle speed reaches a set speed, and automatically lowers the vehicle height when the vehicle speed reaches a vehicle speed lower than or equal to the set speed. More specifically, when the vehicle speed reaches the set speed, the switch is automatically turned on and the electromagneti...

AI Technical Summary

Problems solved by technology

Due to this, the spring seat is pressed down, and accordingly, the vehicle height rises

In addition, when the vehicle speed is equal to or lower than the set speed and the switch is automatically closed, the regulating valve body is attracted, the primary side oil storage chamber communicates with the secondary side oil storage chamber, and the working oil in the working oil chamber passes through the primary side Reservoirs and passages return to the oil chambers of the cylinders, thus lowering the vehicle height
