摘要： An oilless air motor assembly and method useable for driving hydraulic pumps and the like. The air motor assembly comprises a slide valve that moved back and forth relative to a valve sleeve situated about the slide valve. A low friction or lubricious dry seal member is disposed between the slide valve and the valve sleeve, thereby eliminating the need for added oil or lubricant and additionally avoiding the need for precise machining and matching (e.g., honing and lapping) of the slide valve and valve sleeve. Also provided is a kit for converting a previously manufactured air motor assembly that requires oil or added lubricant to an oilless air motor assembly. Such kit comprises the slide valve, valve sleeve and dry seal member as well as other optional parts associated with those elements.

摘要： An electrically driven hydrogen pressure booster for a hydrogen driven vehicle includes an inlet for receiving a gas. Also included is a plurality of chambers for compressing the gas, wherein each of the plurality of chambers includes a piston operably coupled to, and driven by, a crankshaft, wherein the crankshaft is driven by an electric motor. Further included is a pipe for transferring the gas between at least two of the plurality of chambers. Yet further included is an outlet for expelling the gas.
