Latest Patents

Jan Lu's latest patents include a variable refrigerant expansion device with pressure relief. This refrigerant expansion assembly is designed for use in vehicle air conditioning systems. It features an orifice channel that connects an orifice inlet port to an orifice outlet port, including a valve seat. The variable orifice assembly is mounted within the orifice channel and consists of a fixed orifice passage that extends axially through a variable orifice body. This body has a sealing flange that can seal against a valve seat via an orifice spring. Additionally, an orifice bypass valve is included, which features a check ball biased against a ball seat by a bypass spring, allowing some refrigerant to bypass the variable orifice assembly. Furthermore, the refrigerant expansion assembly may also include a burst disk downstream of the variable orifice assembly.

Another notable patent is the refrigerant expansion assembly with pressure relief. This assembly also serves a similar purpose in vehicle air conditioning systems. It comprises a main body that includes an orifice inlet port, an orifice outlet port, and an orifice channel extending between these ports. The assembly features a fixed orifice, an upstream bypass channel, and a downstream bypass channel. A bypass valve flange extends from the main body, forming a bypass chamber connected to both bypass channels. A check ball is mounted in the bypass chamber adjacent to the valve seat, with a spring biasing the check ball into the valve seat.
