Abstract
The present invention is an improved hydraulic booster in which there is a ratio chamber between a power piston and a slave piston. The ratio chamber communicates with a low pressure fluid source through a check means which allows fluid from the low pressure fluid source to flow into the ratio chamber and prevents higher pressure fluid in the ratio chamber from flowing to the low pressure source. The check means can also be modified to allow air to be bled from the low pressure chamber.
